NAME
tin, rtin - Usenet newsreader

DESCRIPTION
tin is a full-screen easy to use Usenet newsreader. It can read news locally (e.g.,
/var/spool/news) or remotely (rtin or tin -r option) via an NNTP (Network News Transport
Protocol) server. It will automatically utilize NOV newsoverview(5) style index files if
available locally or via the NNTP [X]OVER command (RFC2980, RFC3977).

tin has four separate levels of operation: Selection level, Group level, Thread level and
Article level. Use the Help ('h') command to view a list of the commands available at a
particular level.

On startup tin will show a list of the newsgroups found in ${TIN_HOME-
DIR:-"$HOME"}/.newsrc. An arrow '->' or highlighted bar will point to the first newsgroup.
Move to a group by using the terminal arrow keys (terminal dependent) or Down ('j') and Up
('k'). Use PgUp/PgDn (terminal dependent) or PageUp ('^U') (CTRL-U) and PageDown ('^D')
(CTRL-D) to page up/down. Enter a newsgroup by pressing '<CR>'.

The GroupNextUnreadArtOrGrp ('<TAB>') key enters the next newsgroup with unread articles.

EXIT STATUS
0 Successful program execution. No unread news available in batch mode.

1 Usage, syntax, configuration file or network error.

2 Unread news available (batch mode (''-Z'') only).

3 NNTP error.

OPTIONS
-4 Force connecting via IPv4 to the remote NNTP server. Only available when build
with IPv6 support.

-6 Force connecting via IPv6 to the remote NNTP server. Only available when build
with IPv6 support.

-a Toggle ANSI color (default is off).

-A Force authentication on initial connect. Only available when reading via NNTP.

-c Create/update index files for every group in ${TIN_HOMEDIR:-"$HOME"}/.newsrc
or file specified by the ''-f'' option and mark all articles as read.

-d Don't load newsgroup descriptions and servers message of the day (interactive
mode).

-D debug-level
Enter debug-level (1 = NNTP, 2 = filter, 4 = newsrc, 8 = threading, 16 = mem-
ory, 32 = attributes, 64 = misc, 128 = remove existing debug files). For
NNTP-level ''-v'' controls the verbosity of the output.

-f file Use the specified file of subscribed to newsgroups in place of ${TIN_HOME-
DIR:-"$HOME"}/.newsrc.

-g server Use the server and newsrc specified in ${TIN_HOMEDIR:-"$HOME"}/.tin/news-
rctable. Only available when reading via NNTP.

-G article-limit
Limit the number of articles/group to retrieve from the server. If article-
limit is > 0 not more than the last article-limit articles/group are fetched
from the server. If article-limit is < 0 tin will start fetching articles from
your first unread minus absolute value of article-limit. Default is 0, which
means no limit.

-h Help listing all command-line options.

-H Brief introduction to tin that is also shown the first time it is started.

-I dir Directory in which to store newsgroup index files. Default is ${TIN_IN-
DEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news. This option has no effect
if tin retrieves its index files via NNTP and cache_overview_files is turned
off.

-l Get number of articles per group from the ${TIN_LIBDIR:-NEWSLIB-
DIR}"/"${TIN_ACTIVEFILE:-active} file. If reading via NNTP this is done with
the LIST command (RFC3977). This might result in incorrect article counts but
is usually faster than the default which is to read the ${TIN_LIBDIR:-NEWSLIB-
DIR}"/"${TIN_ACTIVEFILE:-active} file (either directly or via LIST) and then
check the article count via NNTP GROUP command (RFC3977) ''-ln''. If reading
via NNTP and LIST COUNTS (RFC6048) is available that is used instead as it
gives more accurate article counts.

-m dir Mailbox directory to use. Default is ${TIN_HOMEDIR:-"$HOME"}/Mail.

-M user Mail unread articles to specified user for later reading. For more information
read section "AUTOMATIC MAILING AND SAVING NEW NEWS".

-n Only load groups from the ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-ac-
tive} file that are subscribed to in the user's ${TIN_HOME-
DIR:-"$HOME"}/.newsrc. This allows a noticeable speedup when connecting via a
slow line, but tin may not be able detect which groups are moderated. See also
''-l''.

-N Mail unread articles to yourself for later reading. For more information read
section "AUTOMATIC MAILING AND SAVING NEW NEWS".

-o Quick post all postponed articles and exit. In order for this to be really
quick, it should be used with ''-n'' if possible.

-p port Port to use if reading via NNTP (default is 119). This also overrides the en-
vironment variable $NNTPPORT if set. Only available when reading via NNTP.

-q Don't check for new newsgroups and skip loading the servers message of the
day.

-Q Quick start. Start tin as quickly as possible. Currently this is equivalent to
''-dnq''.

-r Read news remotely from the default NNTP server specified in the environment
variable $NNTPSERVER or contained in the file /etc/news/server.

-R Read news saved by the ''-S'' option.

-s dir Save/read articles to/in directory. Default is ${TIN_HOMEDIR:-"$HOME"}/News.

-S Save unread articles for later reading by the ''-R'' option. For more informa-
tion read section "AUTOMATIC MAILING AND SAVING NEW NEWS".

-u Create/update index files for every group in ${TIN_HOMEDIR:-"$HOME"}/.newsrc
or file specified by the ''-f'' option. This option is disabled if tin re-
trieves its index files via an NNTP server and cache_overview_files is turned
off.

-v Verbose mode for ''-c'', ''-D'', ''-M'', ''-N'', ''-S'', ''-u'' and ''-Z'' op-
tions. Can be used multiple times to increase verbosity.

-V Print version and date information.

-w Quick mode to post an article and then exit. This option implies ''-d''. In
order for this to be really quick, it should be used with ''-n'' if possible.

-x No-posting mode. You cannot post articles if you use this option.

-X No overwrite mode. ${TIN_HOMEDIR:-"$HOME"}/.newsrc and files in ${TIN_HOME-
DIR:-"$HOME"}/.tin will not be overwritten but may be created if they don't
exist.

-z Only start tin if there is any new/unread news. If there is news tin will po-
sition cursor at first group with unread news. Useful for putting in login
file.

-Z Check if there is any new/unread news and exit with appropriate status. If
''-v'' option is specified the number of unread articles in each group is
printed. An exit code 0 indicates no news, 1 that an error occurred and 2 that
new/unread news exists. Useful for writing scripts.

tin can also dynamically change its options by the OptionMenu ('M') command. Any changes
are written to ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc. For more information see section
"GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES" and tin(5).

A list of groups can be specified after the other command-line options. This can be useful
if you wish to yank in or subscribe to a hand-picked subset of the active newsgroups. See
the section "NEWSGROUP LISTS & WILDCARDS" for the types of pattern that tin understands.

If you specify a single group-name, or a wildcard that matches a single group, then you
will automatically enter that group. Otherwise the normal group selection screen will ap-
pear, but with all the matching groups present too, as though you had yanked just those
groups in.

With the ''-w'' flag a given group-name is used as default group to post to. If more than
one group or a wildcard is specified only the first group respectively the first group
that matches is used.

Once you use SelectYankActive ('y') to yank in all active groups, or SelectToggleReadDis-
play ('r') to toggle the read/unread status, then the command-line groups will be gone.
You can use SelectSyncWithActive ('Y') to reread the ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_AC-
TIVEFILE:-active} file and get them back.

NB: With the ''-n'' flag, only unsubscribed groups in the ${TIN_HOMEDIR:-"$HOME"}/.newsrc
file (or the newsrc-file given by the ''-f'' command-line switch or via ${TIN_HOME-
DIR:-"$HOME"}/.tin/newsrctable) can be matched.

Command-line options have higher priority than attributes and tinrc options. Thus, com-
mand-line option takes precedence over configured values.

USAGE
NEWS ADMINISTRATION
Maintaining Netnews on large networks of machines can be a pretty time consuming job as I
discovered when I was given the job of maintaining our news system and news users.

A user starting tin for the first time can be automatically subscribed to a list of news-
groups that are deemed appropriate by the news administrator. The subscriptions file
should be created in your news lib directory (i.e., ${TIN_LIBDIR:-NEWSLIBDIR}/subscrip-
tions) and should be world readable. If you read news via NNTP, then your news server must
support the LIST SUBSCRIPTIONS command. It is part of the NNTP List Extensions (RFC6048)
and all modern servers should understand it.

SCREEN FORMAT
tin has four separate levels of operation: Selection level, Group level, Thread level and
Article level.

At the Selection level the title displays (the name of the news server and) the number of
subscribed groups (containing new unread articles). The newsgroups are displayed in the
middle of the screen usually with the number of unread articles displayed on the same line
in front, but it can be customized via select_format.

->M 1 2 comp.security.announce Announcements from the CERT abou
M 2 1 news.admin.announce Announcements for news adminstra
3 22 news.software.misc News-related software other than
4 1475 news.software.nntp The Network News Transfer Protoc
X 5 124 news.software.readers Discussion of software used to r

There may also be a character prefixing the line. An explanation follows:

u This group is unsubscribed. To see only your subscribed groups use the Select-
ToggleReadDisplay ('r') or SelectYankActive ('y') toggle keys.

M This is a moderated group. Any posts you make will have to be approved by the
group administrator before it will be made public. tin will ask for confirmation
before you post to a moderated group.

N This is a new newsgroup which has been created since you last used tin. New
newsgroups are not subscribed to by default (However, see the $AUTOSUBSCRIBE /
$AUTOUNSUBSCRIBE environment variables). Subscribe to it in the normal way if
you wish the group to continue to appear in your Selection Menu. Simply ignore
new newsgroups and they will be gone the next time you start tin. You will have
to yank in all the groups to find them in a later session.

D This group no longer exists. If you no longer wish to see this group then unsub-
scribe from it in the normal way. This flag will only appear if you have set
strip_bogus to "ask" in the Options Menu.

X You may no longer make posts to this group. Often a group will be superseded by
a more appropriately named one.

= This group has been renamed and you may no longer post to it. If you do, then
you will receive an error from your news server telling you the correct group to
post to.

At the Group level the title contains the name of the group, the number of conversation
threads, the abbreviated threading method (thread_articles), the limit of articles to get
(if set; getart_limit), the total number of (unread) articles (art_marked_read or
art_marked_unread), the number of hot articles art_marked_selected, the number of read hot
articles (if any; art_marked_read_selected), the number of recent articles (art_marked_re-
cent) and the number of killed articles (art_marked_killed). I.e.:

alt.sources (5B -50/23+ 0* 3o 0K)

The characters after the numbers are depending to the configuration and if your are in
show_only_unread_arts mode or not. Some numbers could be missing if the specific option is
not enabled. It might also contain an 'M', 'X' or '=' (see above; doesn't work with the
''-n'' command-line switch!) if the group is moderated, set to no posting or postings to
it get redirected.

If a thread has unread articles it is marked with art_marked_unread in front of the total
number of articles in the thread. If there are recent articles within the thread it might
be marked with art_marked_recent in front of the total number of articles in the thread --
this is controlled by the recent_time option. If a thread has hot articles in it (see also
section "FILTERING ARTICLES") it's marked with art_marked_selected in front of the total
number of articles in the thread. The number of lines of the first (unread) article in the
thread might also be shown right before the subject -- this is controlled by the show_info
option. The display can be customized via group_format.

At the Thread level the screen usually (depends on the threading method used) looks like
this, but can be customized via thread_format:

Page Down PgDn PageDown (^D or ^F or <SPACE>)
Line Up Up arrow Up (k or ^P)
Line Down Down arrow Down (j or ^N)

COMMON EDITING COMMANDS
An emacs(1) style editing package allows the easy editing of input strings. A history
list allows the easy reuse of previously entered strings. In addition to the cursor keys,
the following commands are available when editing a string:

^A, ^E move to beginning or end of line, respectively.

^F, ^B non-destructive move forward or back one location, respectively.

^D delete the character currently under the cursor, or send EOF if no characters in
the buffer.

^H, <DEL> delete character left of the cursor.

^K delete from cursor to end of line.

^P, ^N move through history, previous and next, respectively.

^L, ^R redraw the current line.

<CR> places line on history list if non-blank, appends newline and returns to the
caller.

<ESC> aborts the present editing operation.

GLOBAL COMMANDS
The following commands are available at all 4 menu levels and always have the same effect.

ShellEscape '!'
Shell escape. ShellEscape by itself will launch a shell, ShellEscape <command>
will run an external <command>. This facility may have been disabled by the Sys-
tem Administrator.

ToggleColor '&'

GLOBAL OPTIONS MENU AND TINRC CONFIGURABLE VARIABLES
At startup, tin reads in the configuration files (see also tin(5)). They contain a list
of variables that can be used to configure the way tin works. If it exists, the global
configuration file, /etc/tin/tinrc is read. After that, the user's own configuration file
is read from ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc. The global file is useful for distribut-
ing system-wide defaults to new users who have no private tinrc yet.

The variables are user configurable by editing ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc di-
rectly. Most of them can also be set in the GLOBAL OPTIONS MENU which is accessed by
pressing OptionMenu ('M') at all levels. It allows the user to customize the behavior of
tin. The options are saved to the file ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc when you exit
tin so don't edit the file directly whilst tin is running.

In the options menu use the cursor keys in the usual way to move around. Use ConfigSelect
('^J' or '<CR>') to 'open' the option you wish to change. You will need to enter a new
value or use '<SPACE>' to toggle the available options. ConfigSelect will save the new
value, '<ESC>' will abort without saving changes.

As with the other menus, RedrawScr ('^L') will redraw the screen. You can use SearchSubjF
('/'), SearchSubjB ('?') and SearchRepeat ('\') to search for a specific option. Use Quit
('q') to exit the option menu and keep your changes. Use QuitTin ('Q') to exit without
keeping your changes.

The options menu provides access to the attributes menu for the current group by the Con-
figToggleAttrib ('<TAB>') command. Pressing ConfigToggleAttrib again toggles back to the
options menu. For more information see section "ATTRIBUTES MENU AND GROUP ATTRIBUTES".

The ConfigScopeMenu ('S') command brings up the scopes menu. For more information see sec-
tion "SCOPES MENU".

Here is a full list of all the available variables. The name in braces is the name of the
corresponding setting in ${TIN_HOMEDIR:-"$HOME"}/.tin/tinrc.

ting can also be toggled in the article viewer. Default is 'No'.

ticles with kill_level set to 0, art_marked_killed and art_marked_read_selected
are only shown once. When you reenter the group the mark will be gone.

1 Kill all arts & show with K will process all articles in the group and therefore
there is a processing overhead when using this option. Killed articles are
threaded as normal but they will be marked with art_marked_killed.

2 Kill all arts and never show will process all articles in the group and therefore
there is a processing overhead when using this option. Killed articles simply does
not get displayed at all.
Default is 0 (Kill only unread arts).

Use 8bit characters in mail headers (mail_8bit_header)
Allows 8bit characters unencoded in the header of mail message. Default is OFF. Turn-
ing it ON is effective only if mail_mime_encoding is also set to 8bit. Leaving it OFF
is safe for most users and compliant to Internet Mail Standard (RFC5322 and RFC2047).
Default is OFF.

Mail address (mail_address)
User's mail address (and full name), if not username@host. This is used when creating
articles, sending mail and when pgp(1) / gpg(1) signing (RFC4880).

MIME encoding in mail messages (mail_mime_encoding)
MIME encoding of the body in mail message, if necessary (8bit, base64, quoted-print-
able, 7bit). Default is quoted-printable.

Quote line when mailing (mail_quote_format)
Format of quote line when replying (via mail) to an article (%A=Address, %D=Date,
%F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Ini-
tials). Default is "In article %M you wrote:"

Format of the mailbox (mailbox_format)
Select one of the following mailbox-formats: MBOXO (default, except on SCO), MBOXRD or
MMDF (default on SCO). See mbox(5) and RFC4155 for more details on MBOXO and MBOXRD
and mmdf(5) for more details about MMDF.

Mail directory (maildir)
The directory where articles/threads are to be saved in mbox(5) format. This feature
is mainly for use with the mutt(1) mail program. It allows the user to save arti-
cles/threads/groups simply by giving '=' as the filename to save to. Default is
${TIN_HOMEDIR:-"$HOME"}/Mail.

Invocation of your mail command (mailer_format)
The format string used to create the mailer command with parameters that is used for
mailing articles to other people. Default is '%M "%T" < %F' (e.g., /bin/mail "iain" <
.article). The flexible format allows other mailers with different command line param-
eters to be used such as
sendmail -oem -t < %F
mutt -s "%S" -- "%T" < "%F"
claws-mail --compose "mailto:%T?subject=%S&insert=%F"
interactive_mailer must be set adequate. The following substitutions are supported:
%F filename
%M default_mailer
%S subject-field
%T to-filed
%U username
%% %

'Mark as (un)read' ignores tags (mark_ignore_tags)
When this is ON, the GroupMarkThdRead ('K'), ThreadMarkArtRead ('K'), MarkThdUnread
('Z') at Group level and MarkArtUnread ('z') at Thread level functions mark just the
current article or thread, ignoring other tagged, (un)read articles. When OFF, the
same function presents a menu with choices of the current thread or article, all
tagged, unread articles, or nothing.

Mark saved articles/threads as read (mark_saved_read)
If ON mark articles that are saved as read. Default is ON.

Viewer program for MIME articles (metamail_prog)
Path, name and options of external metamail(1) program used to view non-textual parts
of articles. To use the built-in viewer, set to --internal. This is the default value
when metamail(1) is not installed. Leave it blank if you don't want any automatic
viewing of non-textual attachments. The PageViewAttach ('V') command can always be
used to manually view any attachments. See also ask_for_metamail.

MM_CHARSET (mm_charset)
Charset supported locally, which is also used for MIME header (charset parameter and
charset name in header encoding) in mail and news postings. If MIME_STRICT_CHARSET is
defined at compile time, text in charset other than the value of this parameter is
considered not displayable and represented as '?'. Otherwise, all character sets are
regarded as compatible with the display. If it's not set, the value of the environment
variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither
of them is defined. If your system supports iconv(3), this option is disabled and you
should use mm_network_charset instead.

MM_NETWORK_CHARSET (mm_network_charset)
Charset used for posting and MIME headers; replaces mm_charset. Conversion between
mm_network_charset and local charset (determined via nl_langinfo(3)) is done via
iconv(3), if this function is not available on your system this option is disabled and
you have to use mm_charset instead. mm_network_charset is limited to one of the fol-
lowing charsets:
US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU} EUC-{CN,JP,KR,TW},
ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
Not all values might work on your system, see iconv_open(3) for more details. If it's
not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or com-
pile-time default is used in case neither of them is defined.

Attribute of highlighting with _dash_ (mono_markdash)
Character attribute of words emphasized like _this_. It depends on your terminal which
attributes are usable. See also word_h_display_marks and word_highlight.

Attribute of highlighting with /slash/ (mono_markslash)
Character attribute of words emphasized like /this/. It depends on your terminal which
attributes are usable. See also word_h_display_marks and word_highlight.

Attribute of highlighting with *stars* (mono_markstar)
Character attribute of words emphasized like *this*. It depends on your terminal which
attributes are usable. See also word_h_display_marks and word_highlight.

Attribute of highlighting with -stroke- (mono_markstroke)
Character attribute of words emphasized like -this-. It depends on your terminal which
attributes are usable. See also word_h_display_marks and word_highlight.

(newnews)
These are internal timers used by tin to keep track of new newsgroups. Do not change
them unless you understand what they are for.

Display these header fields (or *) (news_headers_to_display)
Which news headers you wish to see. If you want to see _all_ the headers, place an '*'
as this value. This is the only way a wildcard can be used. If you enter 'X-' as the
value, you will see all headers beginning with 'X-' (like X-Alan or X-Pape). You can
list more than one by delimiting with spaces. Not defining anything turns off this op-
tion.

Do not display these header fields (news_headers_to_not_display)
Same as news_headers_to_display except it denotes the opposite. An example of using
both options might be if you thought 'X-' headers were A Good Thing(tm), but thought
Alan and Pape were miscreants... well then you would do something like this:
news_headers_to_display=X- news_headers_to_not_display=X-Alan X-Pape Not defining any-
thing turns off this option.

Quote line when following up (news_quote_format)
Format of quote line when posting/following up an article (%A=Address, %D=Date,
%F=Fullname+Address, %G=Groupname, %M=Message-ID, %N=Fullname, %C=Firstname, %I=Ini-
tials). Default is "%F wrote:".

The normalization form tin should use to normalize unicode input. The possible values
are:

0 None: no normalization

1 NFKC: Compatibility Decomposition, followed by Canonical Composition

2 NFKD: Compatibility Decomposition

3 NFC: Canonical Decomposition, followed by Canonical Composition

4 NFD: Canonical Decomposition

5 NFKC_CF: Compatibility Decomposition, followed by Canonical Composition and Case
Folding
Some normalization modes are only available if they are supported by the library tin uses
to do the normalization. NFC should be used if possible.

Go to first unread article in group (pos_first_unread)
If ON put cursor at first unread article in group otherwise at last article. Default
is ON.

Use 8bit characters in news headers (post_8bit_header)
Allows 8bit characters unencoded in the header of a news article, if set this also
disables the generation of MIME-headers when they are usually required. Default is
OFF. Only enacted if post_mime_encoding is also set to 8bit. In a number of local hi-
erarchies where 8bit characters are used, using unencoded (raw) 8bit characters in
header is acceptable and sometimes even recommended so that you need to check the con-
vention adopted in the local hierarchy of your interest to determine what to do with
this and post_mime_encoding.

MIME encoding in news messages (post_mime_encoding)
MIME encoding of the body in news message, if necessary. (8bit, base64, quoted-print-
able, 7bit). Default is 8bit, which leads to no encoding. base64 and quoted-printable
are usually undesired on usenet.

View post-processed files (post_process_view)
If ON, then tin will start an appropriate viewer program to display any files that
were post processed and uudecoded. The program is determined using the mailcap(5)
file. Default is ON.

Post process saved articles (post_process_type)
This specifies whether to perform post processing on saved articles. Because the
shell archive may contain commands you may not want to be executed, be careful when
extracting shell archives. The following values are allowed:

0 No (default), no post processing is done.

1 Shell archives, unpacking of multi-part shar(1) files only.

2 Yes, binary attachments and data will be decoded and saved.

Filename to be used for storing posted articles (posted_articles_file)
Keep posted articles in given file. If the given filename does not contain any expand-
able strings it will be prefixed with ${TIN_HOMEDIR:-"$HOME"}/Mail/. If no filename is
set then postings will not be saved. See the section "MAILING PIPING PRINTING REPOST-
ING AND SAVING ARTICLES" for more information about the various expansion characters.
Default is 'posted'.

Print all headers when printing (print_header)
If ON, then the full article header is sent to the printer. Otherwise only the ''Sub-
ject:'' and ''From:'' fields are output. Default is OFF.

Characters used as quote-marks (quote_chars)
The character used in quoting included text to article followups and mail replies. The
'_' character represents a blank character and is replaced with ' ' when read, %I is
replaced by author's initials. Default is '>_'.

Quoting behavior (quote_style)
How articles should be quoted when following up or replying to them. There are a num-
ber of things that can be done: empty lines can be quoted, signatures can be quoted
and quote_chars can be compressed when quoting multiple times (for example, '> > >'
will be turned into '>>>'). The default is to compress quotes, and to quote empty
lines.
When you are viewing an article in raw mode ('^H'), and follow up or reply to it, the
signature will be quoted even if it would otherwise not be. If show_signatures is
off, then the signature will never be quoted.

Regex used to show quoted lines (quote_regex)
A regular expression that will be applied when reading articles. All matching lines
are shown in col_quote. If quote_regex is blank, then tin uses a built-in default.

Regex used to show twice quoted l. (quote_regex2)
A regular expression that will be applied when reading articles. All matching lines
are shown in col_quote2. If quote_regex2 is blank, then tin uses a built-in default.

Regex used to show >= 3 times q.l. (quote_regex3)

Number of lines to scroll in pager (scroll_lines)
The number of lines that will be scrolled up/down in the article pager when using cur-
sor-up/down. The default is 1 (line-by-line). Set to 0 to get traditional tin page-by-
page scrolling. Set to -1 to get page-by-page scrolling where the top/bottom line is
carried over onto the next page. This setting supersedes show_last_line_prev_page=ON.
Set to -2 to get half-page scrolling. This setting supersedes full_page_scroll=OFF.

Format string for the Selection level (select_format)
Format string tin uses for Selection level representation. See the section "CUSTOMIZ-
ING THE SCREEN FORMAT". Default is "%f %n %U %G %d".

In group and thread level, show author by (show_author)

are displayed (default).

3 Address and Name, ''Subject:'' line & all of the ''From:'' line are displayed.

Show description of each newsgroup (show_description)
If ON show a short group description text after newsgroup name at the group selection
level. The ''-d'' command-line flag will override the setting and turn descriptions
off. The text used is taken from the ${TIN_LIBDIR:-NEWSLIBDIR}/newsgroups file and if
supported (requires tin to be build with mh-mail-handling support) from ${TIN_HOME-
DIR:-"$HOME"}/.tin/mailgroups for mailgroups. Default is ON.

Function for sorting articles (sort_function)
Function used for sorting articles. Default is 0.

0 Use qsort(3) for sorting.

Create signature from path/command (sigfile)
The path that specifies the signature file to use when posting, following up to or re-
plying to an article. If the path is a directory then the signature will be randomly
generated from files that are in the specified directory. If the path starts with a !
the program the path points to will be executed to generate a signature. In order to
pass the group name to the program, %G can be specified. This will be replaced by the
name of the current newsgroup. --none will suppress any signature. Default is
${TIN_HOMEDIR:-"$HOME"}/.Sig.

Add signature when reposting (signature_repost)
If ON add signature to reposted articles. Default is ON.

Regex used to highlight /slashes/ (slashes_regex)

Regex used to highlight *stars* (stars_regex)
A regular expression that will be applied when reading articles. All matching words
are shown in col_markstar or mono_markstar. If stars_regex is blank, then tin uses a
built-in default.

1 Sum, the sum of all scores in this thread.

2 Average, the average score in this thread.

Transliteration (translit)
If ON append //TRANSLIT to the first argument of iconv_open(3) to enable translitera-
tion. This means that when a character cannot be represented in the target character
set, it can be approximated through one or several similarly looking characters. On
systems where this extension doesn't exist, this option is disabled. Default is OFF.

How to treat blank lines (trim_article_body)
Allows you to select how tin treats blank lines in article bodies. Default is 0. This
option does not affect lines within verbatim blocks.

0 Don't trim article body, do nothing.

Use mouse in xterm (use_mouse)
Allows the mouse button support in an xterm(1x) to be enabled/disabled. Default is
OFF.

Use slrnface to show ''X-Face:''s (use_slrnface)
If enabled tin uses slrnface(1) to interpret the ''X-Face:'' header. For this option
to have any effect, tin must be running in an xterm(1x) and slrnface(1) must be in
your $PATH. Default is OFF.

Use UTF-8 graphics (utf8_graphics)
If ON use UTF-8 characters for indicator ('->'), thread/attachment tree and ellipsis
('...'). Default is OFF.

Regex for begin of a verbatim block (verbatim_begin_regex)
A regular expression that tin will use to find the begin of a verbatim block.

Regex for end of a verbatim block (verbatim_end_regex)

Detection of verbatim blocks (verbatim_handling)
If ON verbatim blocks will be detected. Default is ON.

Wildcard matching (wildcard)
Allows you to select how tin matches strings. The default is 0 and uses the wildmat(3)
notation, which is how this has traditionally been handled. Setting this to 1 allows
you to use perl(1) compatible regular expressions pcre(3) (see also perlre(1) and
pcrepattern(3)). You will probably want to update your filter file if you use this
regularly. NB: Newsgroup names will always be matched using the wildmat(3) notation.

What to display instead of mark (word_h_display_marks)
Should the leading and ending stars, slashes, strokes and dashes also be displayed,
even when they are highlighting marks?

0 no

1 yes, display mark

2 print a space instead

Word highlighting in message body (word_highlight)
Enable word highlighting. See word_h_display_marks for the options available. If
use_color is enabled the colors specified in col_markdash, col_markslash, col_markstar
and col_markstroke are used for word highlighting else the character attributes speci-
fied in mono_markdash, mono_markslash, mono_markstar and mono_markstroke are used. De-
fault is ON.

Page line wrap column (wrap_column)
Sets the column at which a displayed article body should be wrapped. If this value is
equal to 0, it defaults to the current screen width. If this value is greater than
your current screen width the part off-screen is not displayed. Thus setting this op-
tion to a large value can be used to disable wrapping. If this value is negative the
wrap margin is the current screen width plus the given value (as long as the result is
still positive, otherwise it will fall back to the current screen width). Default is
0, wrapping at the current screen width.

Quote line when crossposting (xpost_quote_format)
Format is the same as for news_quote_format, this is used when answering to a cross-
posting to several groups with no ''Followup-To:'' set.

ATTRIBUTES MENU AND GROUP ATTRIBUTES
tin allows certain attributes to be set on a per group basis. If it exists, the global at-
tributes file, ${TIN_LIBDIR:-NEWSLIBDIR}/attributes is read. After that, the user's own
attributes file ${TIN_HOMEDIR:-"$HOME"}/.tin/attributes is read. The global attributes
file is useful for distributing system-wide defaults to new users who have no private at-
tributes file yet.

Note that the scope=<grouplist> line has to be specified before the attributes are speci-
fied for that list. All attributes are set to a reasonable default so you only have to
specify the attribute that you want to change (e.g., savedir). All toggle attributes are
set by specifying ON/OFF. Otherwise, these function exactly the same as their global
equivalents. For more details see tin(5).

Attributes can also be changed from the attributes menu which can be accessed by Config-
ToggleAttrib ('<TAB>') from the options menu or ScopeSelect ('^J' or '<CR>') from the
scopes menu. The attributes menu looks and behaves very similar to the options menu. The
title shows the current scope. Attributes set in the current scope are marked with '+' to
the left of the attributes number.

Besides the keys for moving around and changing values known from the options menu the at-
tributes menu provides the following command: ConfigResetAttrib ('r') which resets an at-
tribute to a default value.

SCOPES MENU
The scopes menu (accessible from the options menu with ConfigScopeMenu ('S')) shows all
scopes read from the global and local attributes file. Scopes from the global attributes
file are marked with '!' to the left of the scope number. Delete/rename/move are not pos-
sible with those scopes.

In addition to the common moving keys the following commands are available: ScopeSelect
('^J' or '<CR>') enter the attributes menu for the current scope, ScopeEditAttributesFile
('E') edit the local attributes file, ScopeAdd ('a') add a new scope, ScopeDelete ('d')
delete the current scope, ScopeMove ('m') move the current scope to a new position, Scop-
eRename ('r') rename the current scope. ToggleHelpDisplay ('H') toggles the help mini menu
at the bottom of the screen and posting etiquette after composing an article (begin-
ner_level).

FILTERING ARTICLES
When there is a subject or an author which you are either very interested in, or find com-
pletely uninteresting, you can easily instruct tin to auto-select or auto-kill articles
that match rules that you specify. This can be anything from the name of the author to the
number of lines in an article.

When tin starts up the user's kill-file ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (see also
tin(5)) is read. Each time a newsgroup is entered the rules are applied and articles
killed or selected when they meet certain criteria.

The degree to which rules are applied depend on the kill_level tinrc setting. By default
killed articles will only be marked read. Adjust kill_level for more aggressive process-
ing. Articles that match an auto-selection rule are marked with a ''*''.

Filtering rules can be manually entered into ${TIN_HOMEDIR:-"$HOME"}/.tin/filter (but
don't do this whilst running tin else you will lose your changes) or by using an on-screen
menu within tin.

The filtering capabilities of tin have been significantly enhanced over previous versions
to include scoring and better pattern matching. It is recommended that you read the file
filtering in the tin documentation directory. This file can also be read online at
<http://www.tin.org/filtering.txt>.

The on-screen filtering menu is accessed by pressing MenuFilterKill ('^K') or MenuFilterS-
elect ('^A') at the Group and Article levels. It allows the user to kill or select an ar-
ticle that matches the current ''Subject:'' line, ''From:'' line or a string entered by
the user. The user entered string can be applied to the ''Subject:'' or ''From:'' line of
an article. The filter can be limited to the current newsgroup or it can apply to all
newsgroups. Once entered the user can abort the command and not save the new filter, edit
the full filter file or save filter.

POSTING ARTICLES
tin allows posting of articles, follow-up to already posted articles and replying direct
through mail to the author of an article.

Use the Post ('w') command to post an article to a newsgroup. After entering the post
subject the default editor (i.e., vi(1)) or the editor specified by the $VISUAL or $EDITOR
environment variable will be started and the article can be entered. To crosspost articles
simply add a comma and the name of the newsgroup(s) to the end of the ''Newsgroups:'' line
at the beginning of the article. After saving and exiting the editor you are asked if you
wish to a)bort posting the article, e)dit the article again or p)ost the article to the
specified newsgroup(s).

Use the DisplayPostHist ('W') command to display a history of the articles you have
posted. The date the article was posted, which newsgroups the article was posted to and
the articles subject line are displayed. See the section "POSTING HISTORY LISTING" for
more information.

Use the PageFollowupQuote ('f'), PageFollowup ('F') or PageFollowupQuoteHeaders ('^W')
command to post a follow-up article to an already posted article. The PageFollowupQuote
command will copy the text of the original article into the editor. The PageFollowupQuote-
Headers command will copy the text and all headers of the original article into the edi-
tor. The editing procedure is the same as when posting an article with the Post ('w') com-
mand.

Use the PageReplyQuote ('r'), PageReply ('R') or PageReplyQuoteHeaders ('^E') command to
reply direct through mail to the author of an already posted article. The PageReplyQuote
command will copy the text of the original article into the editor. The PageReplyQuote-
Headers command will copy the text and all headers of the original article into the edi-
tor. The editing procedure is the same as when posting an article with the Post ('w') com-
mand. After saving and exiting the editor you are asked if you wish to abort sending the
article via PostAbort ('a'), edit the article again via PostEdit ('e') or send the article
to the author via PostSend ('s').

CUSTOMIZING THE ARTICLE QUOTE STRING
When posting a followup to an article or replying direct to the author of an article via
email the text of the article can be quoted. The beginning of the quoted text can contain
information about the quoted article (e.g., Name and the Message-ID of the article). To
allow for different situations certain information from the article can be used in the
quoted string. The following variables are expanded if found in the tinrc variables
mail_quote_format, news_quote_format or xpost_quote_format:
%A Address (Email)
%D Date (uses date_format)
%F Full address (%N <%A>)
%G Groupname
%M Message-ID
%N Fullname of author
%C Firstname of author
%I Initials of author
e.g.,
mail_quote_format=On %D in %G you wrote:
news_quote_format=In %M, %F wrote:
would expand to:

The quoted text section of an article is marked by a preceding quote string at the begin-
ning of each quoted line. The default quote string is set to '>_'. The default can be
changed by setting the tinrc variable quote_chars to ones own preference. (Note that '_'
underline is used to represent a space).

MAILING PIPING PRINTING REPOSTING AND SAVING ARTICLES
The command interface to GroupMail, PageMail, PostMail or ThreadMail ('m'), Pipe ('|'),
Print ('o'), PageRepost or GroupRepost ('x') and GroupSave, PageSave or ThreadSave ('s'
and GroupAutoSave, PageAutoSave or ThreadAutoSave 'S') articles is the same for ease of
use.

Auto-saving with *AutoSave ('S') is a special case and operates only on marked articles.
They will processed without any further prompting according to the default save parameters
defined in tinrc or by any attributes set for the current group.

Otherwise, the initial prompt will ask you to select which article, thread, hot (auto-se-
lected), regular expression pattern, tagged articles you wish to mail, pipe etc.

Tagged articles must have already been tagged with a *Tag ('t') command. All tagged arti-
cles can be untagged by a *Untag ('U') untag command.

If a regular expression pattern is selected you are asked to enter a pattern (e.g., to
match all articles subject lines containing 'net News' you enter "net News"). Any articles
that match the entered expression will be mailed, piped etc. See also the wildcard tinrc
variable for advanced pattern matching options.

Various expansion characters are recognized when entering the directory and file to save
to. Environment variables (prefixed with '$') and user home directories (prefixed by '~'
or '~username') can be specified. Environment variables can themselves contain other spe-
cial characters.

To save articles to a mailbox enter '=<mailbox name>' when asked for the save filename. If
you enter just '=' then articles will be saved to a mailbox with the name of the current
newsgroup (eg, alt.sources). See maildir.

To save in savedir/<news.group.name>/<filename> format enter '+<filename>'. See savedir.
Like '+' %G is expanded to the current news.group.name but without savedir prefixed. %P is
expanded to the news.group.name with all '.' replaced by '/'.

If saving multiple files at once the filename (if not referring to a mailbox) will be ex-
tended by ".num" where "num" is at least 3 digit number counting up from 1. Environment
variables are allowed within a filename (e.g., $SOURCES/dir/filename).

When saving articles you can specify whether the saved files should be post processed. A
default process type can be set via post_process_type.

AUTOMATIC MAILING AND SAVING NEW NEWS
tin allows new/unread news articles to be mailed (''-M'' and ''-N'' option) or saved
(''-S'' option) in batch mode for later reading. Useful when going on holiday and you
don't want to return and find that expire has removed a whole load of unread articles.
Best to run via cron(8) everyday while away, after which you will be mailed a report of
which articles were mailed/saved from which newsgroups and the total number of articles
mailed/saved. Articles are saved in a private news structure under your savedir directory
(default is ${TIN_HOMEDIR:-"$HOME"}/News). Be careful of using this option if you read a
lot of groups because you could overflow your file system.

When using ''-S'' together with a given directory to save to (''-s'' option), the same di-
rectory must be specified when reading the articles by ''-R''.

If you only want to save some of your groups use the batch_save tinrc variable. Set to ON
or OFF in tinrc to enable/disable saving of all groups and then use the batch_save attri-
bute to fine tune which groups you want to have saved. For example, if you want to save
most of your groups, then set batch_save to ON in tinrc and selectively turn off the ones
you don't want using attributes.

tin -M iain -c -f newsrc.mail
(mail any unread articles in newsgroups specified in file newsrc.mail
to the local user iain and mark them as read)

tin -S -c -f newsrc.save
(save any unread articles in newsgroups specified in file newsrc.save
and mark them as read)

tin -R (read any articles saved by tin -S)

RANGES
A range is simply a group of items marked using the SetRange ('#') key. Certain tin com-
mands will operate on a range if one exists rather than just the current item. A range is
an expression of the form <min>-<max>, e.g. 10-15 will highlight items 10 through 15 on
the current screen. Other than absolute numeric positions, '.' can be used in place of the
current cursor position and '$' can be used to mean the highest number available. Cur-
rently the only commands that understand ranges are GroupMarkThdRead ('K'), MarkArtUnread
('z') and MarkThdUnread ('Z').

NEWSGROUP LISTS & WILDCARDS
Several places in tin allow you to specify a list of newsgroups. These include command-
line groups, (un)subscribe groups, the AUTO[UN]SUBSCRIBE mechanism. The scope= attributes
file tag and the filter file group= tag also use the same syntax. tin interprets this
variable similarly to rn(1). It contains a list of patterns, separated by commas and pos-
sibly prefixed with exclamation points. An exclamation point negates the meaning of a
match on this pattern, and can be used to cancel certain matches. See wildmat(3) for de-
tails about the understood patterns. Some examples:

alt.config,news.*,!news.test

Matches alt.config and everything in the 'news' hierarchy except news.test

See the explanation for the $AUTOSUBSCRIBE and $AUTOUNSUBSCRIBE variables for further ex-
amples.

SIGNATURES
tin will recognize a signature in either ${TIN_HOMEDIR:-"$HOME"}/.signature or ${TIN_HOME-
DIR:-"$HOME"}/.Sig. If ${TIN_HOMEDIR:-"$HOME"}/.signature exists, then the signature will
be pulled into the editor for mail commands only. A signature in ${TIN_HOME-
DIR:-"$HOME"}/.signature will not be pulled into the editor for posting commands since
inews(1) will append the signature itself.

A signature in ${TIN_HOMEDIR:-"$HOME"}/.Sig will be pulled into the editor for both post-
ing and mailing commands.

The following is an example of a .Sig file:
NAMES Joe Bar <joe AT example.org>
SNAIL Musterweg 12, 99999 Notreal, Germany

tin also has the capability to generate random signatures on a per newsgroup basis if so
desired. The way to accomplish this is to specify the default signature or the group at-
tribute sigfile as a directory. If for example the sigfile path is /usr/iain/.sigs and
.sigs is a directory then tin will select a random signature from any file that is in the
directory .sigs (note: one signature per numbered file). A random signature can also con-
sist of a fixed part signature that can contain your name, address etc. followed by the
random sig. The fixed part of the random sig is read from the file $HOME/.sigfixed.

CUSTOMIZING THE SCREEN FORMAT
The look of the Selection, Group and Thread level can be customized via format strings.
These format strings define the content and the position of each element on the screen.
Variables are used within the format strings as placeholders. The following variables are
available:

%D date
%F from, name and/or address
%G newsgroup name
%I initials
%L line count
%M message-id
%R number of responses in thread
%S score
%T thread tree
%U unread count
%d newsgroup description
%f newsgroup flag
%m article marks
%n current group/thread/article number
%s subject
%% %

Not all variables can be used in each level. The following table provides an overview:

select_format group_format thread_format
%D X X
%F X X
%G X
%I X X
%L X X
%M X X
%R X
%S X X
%T X
%U X
%d X
%f X
%m X X
%n X X X
%s X
%% X X X

Defaults for the format strings:

select_format: "%f %n %U %G %d"
group_format: "%n %m %R %L %s %F"
thread_format: "%n %m [%L] %T %F"

show_description controls whether the newsgroup description is shown or not. The descrip-
tion can also be toggled with SelectToggleDescriptions ('d').

The information displayed with '%F' depends on the value of show_author. GroupToggleSub-
jDisplay resp. ThreadToggleSubjDisplay ('d') switches through all available options.

For date representation '%D' uses date_format. It is possible to specify a different date
format in round brackets (e.g. '%(%d %b %y %H:%M)D'). See date_format for more details.

The length of each item (except '%%') can be defined with a positive number after the '%'.
The following example displays the score in the thread level 10 characters wide: '%10S'.

If the newsgroup name is displayed together with the newsgroup description, the width of
the newsgroup name can be controlled via an optional comma separated second value (e.g.
'%60,20G'). It is valid to omit the first value (e.g. ('%,20G')). If no second value is
given, tin uses a default value of 32.

Some variables do have a default width which may lead to truncation. Truncation for vari-
ables which contain only numbers happens by dividing the value with a sufficient power of
ten and adding a SI suffix to the result, that is the variable holds a value of 54321 and
the width for the variable is 4 the result will be "54 k". If that's undesired you have to
specify a larger width manually, e.g. '%6n'. Here is an overview of the defaults:

Variable width
%I 3
%L 4
%M 10
%R 3
%S 6
%U 5
%n 4

If no length is given for '%D', the length is determined by the format string for the date
and the date of the current day. If the date format string contains weekdays or months
names it may happen that the date is longer than determined in the first pass. In this
case, the date is truncated before display. This occurs, for example, if the current month
is May and the article to which the date is displayed was posted in December. In such
cases it might useful to determine the maximum length manually and specify the length in
the format string.

In case the format string contains '%G' and '%d' and no length are given, tin determines
the longest newsgroup name and uses this length for '%G'. The remaining space will used
for '%d'.

When the format string contains the specifier '%F' and '%s' resp. '%T' and no length are
given, '%F' will use one third and '%s' resp. '%T' will use two third of the available
space.

In addition, a minimum screen width can be defined for each item (except '%%'). In this
case, the item will only be displayed when the screen is wider than specified. This comes
in handy to not overload a small screen but have maximum information on a large screen.
The minimum screen width has to be specified by a positive number preceded by an '>'. In
the following example tin will display the score only if the screen is wider than 100
characters: '%>100S'.

If both the length and the minimum screen width should be specified for an item, the
length must be the first parameter and the minimum screen width must be the second one.
The following example displays the score with a length of 10 characters only if the screen
is wider than 100 characters: '%10>100S'.

TIPS AND TRICKS
tin can be pretty much be navigated by using the four cursor keys. The left arrow key
goes up a level, the right arrow key goes down a level, the up arrow key goes up a line
and the down arrow key goes down a line.

The following newsgroups provide useful information concerning news software:
--news.software.readers (info. about news user agents tin, rn, nn, slrn etc.)
--news.software.nntp (info. about NNTP)
--news.answers (Frequently Asked Questions (FAQ) about many different themes)

Many prompts within tin offer a default choice that the cursor is positioned on. By press-
ing '<CR>' the default value is taken. Most prompts can be aborted by pressing '<ESC>'.

When tin is run in an xterm(1x) it will resize itself each time the xterm(1x) is resized.

tin will reread the ${TIN_LIBDIR:-NEWSLIBDIR}"/"${TIN_ACTIVEFILE:-active} file at set in-
tervals (reread_active_file_secs) to show any newly arrived news.

If you find large number of new newsgroups cluttering up your screen, pressing SelectTog-
gleReadDisplay ('r') will make them go away.

XTERM BUTTONS
If the environment variable $TERM is set to xterm(1x), then button pressing can be used to
select groups and articles. In this discussion, the buttons are assumed to be assigned
conventionally (i.e., Button1 is the left button).

In general (i.e., for the group, thread and article menus),

Button1 (left)
enters next (lower) level if you click on an article, otherwise pages down.

Button2 (center)
returns to the previous (upper) level if you click on an article, otherwise
pages up.

Button3 (right)
positions on the article line under mouse cursor, or pages down if you've
clicked outside the list of articles.

In the group selection menu, if the mouse is pointing at a group then:

left button
moves to and selects the group pointed at, just like SelectReadGrp ('<CR>').

center button
quits the program, just like Quit ('q').

right button
moves to the group pointed at.

In the article menu, if the mouse is pointing at an article (or thread) then:

left button
reads the article pointed at, just like GroupReadBasenote ('<CR>'), or the
thread, just like GroupListThd ('l').

center button
exits the menu, catching up on the group if you have group_catchup_on_exit set
in your configuration, just like Quit ('q').

right button
moves to the article (or thread) pointed at.

In the thread menu, if the mouse is pointing at an article then:

left button
reads article pointed at, just like ThreadReadArt ('<CR>').

center button
exits the menu, catching up on the thread if you have thread_catchup_on_exit set
in your configuration, just like Quit ('q').

right button
moves to the article pointed at.

In other menus and areas button pressing reverts back to usual cut and paste of xterm(1x),
but after one click of any button.

INDEX FILES
If your news server supports NOV index files (see newsoverview(5), most modern installa-
tions will) and you have a fast connection to your news server then this section can be
ignored.

If your news server doesn't support NOV index files or you have a very slow connection to
your news server then tin can cache the index for each newsgroup if cache_overview_files
is set to ON. Note that this cache can use up large amounts of disk space if you read a
lot of groups and/or high traffic groups.

Each user creates/updates his/her own index files that are stored in ${TIN_INDEX_NEWS-
DIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news/. If you are reading via NNTP then the news
server name will be appended to keep the indexes for different servers separate. If you
are reading off the local spool and local overview files already exist then turning on
caching will have no effect. Likewise unless you see significant delays entering a group
when reading via NNTP then turning on caching will have little or no effect.

Entering a group the first time tends to be slow because the index file must be built from
scratch. To alleviate the slowness start tin to create all index files for the groups you
subscribe to with tin -u -v and go for a coffee. Subsequent readings of a group will only
need to do incremental updating of the index file and will be much faster as only new ar-
ticles will need to be cached.

As indexing might take some time you may want to run tin from the system batcher cron(8)
with the ''-u'' option:

30 6 * * * /usr/local/bin/tin -u

If you are low on local disk space you should consider to manually purge cached data for
groups you are not reading anymore with something like:

find ${TIN_INDEX_NEWSDIR:-"${TIN_HOMEDIR:-"$HOME"}/.tin"}/.news* \
-type f -name "[0-9]*.[0-9]" -atime +28 | xargs rm -f

ENVIRONMENT
TINRC Define this variable if you want to specify command-line options that tin should be
started with to save typing them each time it is started. The contents of the envi-
ronment variable are added to the front of the command-line options before it is
parsed therefore allowing an option specified on the command-line to override the
same option specified in the environment.

TIN_HOMEDIR
Define this variable if you do not want the .tin directory in $HOME/. E.g., if you
want all tin's private files in /tmp/.tin you would set $TIN_HOMEDIR to /tmp.

TIN_INDEX_NEWSDIR
Define this variable if you do not want the .news directory in ${TIN_HOME-
DIR:-"$HOME"}/.tin/. E.g., if you want all tin's news index files in /tmp/.news you
would set $TIN_INDEX_NEWSDIR to /tmp.

TIN_INDEX_MAILDIR
Define this variable if you do not want the .mail directory in ${TIN_HOME-
DIR:-"$HOME"}/.tin/. E.g., if you want all tin's mail index files in /tmp/.mail you
would set $TIN_INDEX_MAILDIR to /tmp.

TIN_INDEX_SAVEDIR
Define this variable if you do not want the .save directory in ${TIN_HOME-
DIR:-"$HOME"}/.tin/. E.g., if you want all tin's save index files in /tmp/.save you
would set $TIN_INDEX_SAVEDIR to /tmp.

TIN_LIBDIR
Define this variable if you want to override the NEWSLIBDIR path that was compiled
into the tin binary, default is /usr/lib/news. If tin is running in NNTP mode set-
ting this variable has no effect.

TIN_SPOOLDIR
Define this variable if you want to override the SPOOLDIR path that was compiled
into the tin binary, default is /var/spool/news. If tin is running in NNTP mode
setting this variable has no effect.

TIN_NOVROOTDIR
Define this variable if you want to override the NOVROOTDIR path that was compiled
into the tin binary, default is SPOOLDIR (see above). If tin is running in NNTP
mode setting this variable has no effect.

TIN_NOVFILENAME
Define this variable if you want to override the OVERVIEW_FILE filename that was
compiled into the tin binary, default is .overview. If tin is running in NNTP mode
setting this variable has no effect.

TIN_ACTIVEFILE
Define this variable if you want to override the NEWSLIBDIR/active path that was
compiled into the tin binary. If tin is running in NNTP mode setting this variable
has no effect. If $TIN_LIBDIR is set it is prepended to $TIN_ACTIVEFILE.

NNTPSERVER
The default NNTP server to remotely read news from. This variable only needs to be
set if the ''-r'' command-line option is specified and the file /etc/news/server
does not exist. The ''-g'' command line option overrides $NNTPSERVER.

NNTPPORT
The NNTP TCP-port to read news from. This variable only needs to be set if the TCP-
port is not 119 (the default). The ''-p'' command-line option overrides $NNTPPORT.

DISTRIBUTION
Set the article header field ''Distribution:'' to the contents of the variable in-
stead of the system default.

ISO2ASC
Set the ISO to ASCII charset decoding table character to use in decoding an article
text. Values can range from -1 to 6.

-1 no conversion

0 universal table for many languages

1 single-spacing universal table

2 table for Danish, Dutch, German, Norwegian and Swedish

3 table for Danish, Finnish, Norwegian and Swedish using the appropriate ISO 646
variant

4 table with RFC1345 codes in brackets

5 table for printers that allow overstriking with backspace

6 table for IBM PC character set (code page 437)

ORGANIZATION
Set the article header field ''Organization:'' to the contents of the variable in-
stead of the system default. If reading news on an Apollo DomainOS machine the en-
vironment variable $NEWSORG has to be used instead of $ORGANIZATION.

NEWSORG (DomainOS)
DomainOS specific, same as $ORGANIZATION on other OSs (see above).

REPLYTO
Set the article header field ''Reply-To:'' to the return address specified by the
variable. This is useful if you wish to receive replies at a different address.

NAME Overrides the full name given in the gecos-field in /etc/passwd, see also mail_ad-
dress.

REALNAME
Same as $NAME.

HOME Pathname of the user's home directory. See environ(5) for more info.

MAILER This variable has precedence over the default mailer that is used in all mailing
operations within tin.

MAIL Full path to the user's mailbox.

VISUAL This variable has precedence over the default editor (i.e., vi(1)) that is used in
all editing operations within tin (e.g., posting, replying, follow-ups, ...). Eval-
uation order is ${VISUAL:-"${EDITOR:-vi}"}. See environ(5) for more info.

EDITOR If $VISUAL is unset, then this variable is looked up for a default editor. If $EDI-
TOR and $VISUAL are both unset, tin uses the systems default editor (i.e. vi(1) on
UNIX-systems). See environ(5) for more info.

AUTOSUBSCRIBE
A new group is checked against the list of patterns; if it matches, tin subscribes
the user to the group without further query. See the section "NEWSGROUP LISTS &
WILDCARDS" for an explanation of the valid syntax. For example, setting

AUTOSUBSCRIBE=comp.os.unix.*,talk.*,!talk.politics.*

will automatically subscribe the user to all new groups in the comp.os.unix hierar-
chy, and all talk groups other than talk.politics groups (which will be queried for
as usual). Of course this does not work if tin is started with the ''-X'' command-
line switch.

AUTOUNSUBSCRIBE
Is handled like the $AUTOSUBSCRIBE variable, but groups matching the list are un-
subscribed from without further query. For example, setting

AUTOUNSUBSCRIBE=alt.flame.*,u*,!uk.*

will automatically unsubscribe the user from all new alt.flame groups and all
groups starting with u (university groups) other than UK groups (which will be
queried for as usual).

TMPDIR A pathname of a directory made available for tin to create temporary files.

MAILCAPS
This variable can be used to override the default path search for mailcap(5) files.
See also tin(5).

NOMETAMAIL
Set this variable to disable the use of metamail(1) or a replacement (e.g. meta-
mutt).

MM_CHARSET
MIME character set used if not configured via the tinrc variable mm_charset.

ISPELL Set this variable to point to ispell(1) or a replacement and its cmd-line options.

PGPOPTS
Define any additional options that you wish to pass to your pgp(1) or gpg(1) pro-
gram.

PGPPATH
Override the name of the pgp(1) directory in $HOME that holds your keys etc..

GNUPGHOME
Override the name of the gpg(1) directory in $HOME that holds your keys etc..

LC_CTYPE
This variable determines the locale(5) category for character handling functions.
Usually it determines the character classes for pattern matching character classi-
fication and case conversion. Currently this is not true for tin (which temporary
unsets $LC_CTYPE right before any match is done to avoid confusion). It's value
should be of the form language[_territory][.codeset][@modifier]. See environ(5) for
more information.

LC_MESSAGES
Formats of informative and diagnostic messages and interactive responses. It's
value should be of the form language[_territory][.codeset][@modifier]. See
locale(5) and environ(5) for more information.

LC_TIME
Date and time formats. It's value should be of the form language[_territory][.code-
set][@modifier]. See locale(5) and environ(5) for more information.

LC_ALL This variable overrides the value of the $LANG variable and any other $LC_ vari-
able. It's value should be of the form language[_territory][.codeset]. See
locale(5) and environ(5) for more information.

LANG This variable determines the locale(5) category for any category not specifically
selected with a variable starting with $LC_. It's value should be of the form lan-
guage[_territory][.codeset]. See environ(5) for more information.

LANGUAGE
This variable defines a priority list for translations. Whenever a translation is
not available in the language selected via $LC_ALL or $LANG the next language from
the list is tried. It's value should be of the form language:language[:language].
See environ(5) for more information.

COLUMNS
A decimal integer > 0 used to indicate the user's preferred width in column posi-
tions for the terminal screen or window. If this variable is unset or null, the im-
plementation determines the number of columns, appropriate for the terminal or win-
dow. When $COLUMNS is set, any terminal-width information implied by $TERM will be
overridden. Users and portable applications should not set $COLUMNS unless they
wish to override the system selection and produce output unrelated to the terminal
characteristics.

LINES A decimal integer > 0 used to indicate the user's preferred number of lines on a
page or the vertical screen or window size in lines. A line in this case is a ver-
tical measure large enough to hold the tallest character in the character set being
displayed. If this variable is unset or null, the implementation determines the
number of lines, appropriate for the terminal or window. When $LINES is set, any
terminal-height information implied by $TERM will be overridden. Users and portable
applications should not set $LINES unless they wish to override the system selec-
tion.

TERM The type of terminal in use. This is used when looking up termcap sequences. See
environ(5) for more information.

DISPLAY
Display name, pointing to the X server; required for xface.

WINDOWID
Used for determining terminal's X window id; required for xface. Should be set by
the terminal emulator.

SHELL The pathname of the user's login shell. Used to set default_shell_command.

XDG_RUNTIME_DIR
The pathname of the user's dir to put non-essential run time files into.

SIGNALS
tin handles a couple of signals:

SIGHUP Terminate gracefully.

SIGTERM
Terminate gracefully.

SIGUSR1
Terminate gracefully but do not restore terminal (tty).

SIGUSR2
Write out ${TIN_HOMEDIR:-"$HOME"}/.newsrc-file.

SECURITY
If tin is started in debug mode (''-D n'') it will create world readable files in $TMPDIR
which may contain the users NNTP password in cleartext. On multiuser-systems $TMPDIR
should be set to a safe location before starting tin in debug mode (e.g. TMPDIR=$HOME tin
-D 1).

CONFORMING TO
tin does conform to the Base Definitions volume of IEEE Std 1003.1-2008, Section 12, Util-
ity Conventions (Utility Argument Syntax, Utility Syntax Guidelines).

NOTES
Regular expression support is provided by the PCRE library package pcre(3), which is open
source software, written by Philip Hazel, and copyright by the University of Cambridge,
England.

BUGS
CNews NNTPd, noffle(1) (<= V1.0-pre5) and NewsCache (<= V1.1.91) can't handle pipelined
GROUP commands. If you run into trouble with any of the mentioned servers define DIS-
ABLE_PIPELINING in include/autoconf.h and recompile.
Before mailing a bug-report to <tin-bugs AT tin.org> please check if you are using the latest
(stable) release, and if not, please upgrade first! Have a look at the doc/TODO file for
known bugs. If you still think you've found a bug, please use the BugReport ('R') function
and write in English. Please do NOT enclose a core-file in your bug-report until we re-
quest it.

HISTORY
tin is based on the tass(1) newsreader that was developed by Rich Skrenta and posted to
alt.sources in March 1991; its first version was released on August 23rd 1991. tass(1)
itself was heavily influenced by notesfiles a public domain UNIX version of PLATO Notes,
developed at the University of Illinois by Ray Essick and Rob Kolstad in 1982. For a ver-
sion overview see
