NAME
size - list section sizes and total size of binary files

SYNOPSIS
size [-A|-B|-G|--format=compatibility]
[--help]
[-d|-o|-x|--radix=number]
[--common]
[-t|--totals]
[--target=bfdname] [-V|--version]
[objfile...]

DESCRIPTION
The GNU size utility lists the section sizes and the total size for each of the binary
files objfile on its argument list. By default, one line of output is generated for each
file or each module if the file is an archive.

objfile... are the files to be examined. If none are specified, the file "a.out" will be
used instead.

OPTIONS
The command-line options have the following meanings:

-A
-B
-G
--format=compatibility
Using one of these options, you can choose whether the output from GNU size resembles
output from System V size (using -A, or --format=sysv), or Berkeley size (using -B, or
--format=berkeley). The default is the one-line format similar to Berkeley's.
Alternatively, you can choose the GNU format output (using -G, or --format=gnu), this
is similar to Berkeley's output format, but sizes are counted differently.

Here is an example of the Berkeley (default) format of output from size:

$ size --format=Berkeley ranlib size
text data bss dec hex filename
294880 81920 11592 388392 5ed28 ranlib
294880 81920 11888 388688 5ee50 size

The Berkeley style output counts read only data in the "text" column, not in the
"data" column, the "dec" and "hex" columns both display the sum of the "text", "data",
and "bss" columns in decimal and hexadecimal respectively.

The GNU format counts read only data in the "data" column, not the "text" column, and
only displays the sum of the "text", "data", and "bss" columns once, in the "total"
column. The --radix option can be used to change the number base for all columns.
Here is the same data displayed with GNU conventions:

$ size --format=GNU ranlib size
text data bss total filename
279880 96920 11592 388392 ranlib
279880 96920 11888 388688 size

This is the same data, but displayed closer to System V conventions:

$ size --format=SysV ranlib size
ranlib :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11592 385024
Total 388392

size :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11888 385024
Total 388688

--help
Show a summary of acceptable arguments and options.

-d
-o
-x
--radix=number
Using one of these options, you can control whether the size of each section is given
in decimal (-d, or --radix=10); octal (-o, or --radix=8); or hexadecimal (-x, or
--radix=16). In --radix=number, only the three values (8, 10, 16) are supported. The
total size is always given in two radices; decimal and hexadecimal for -d or -x
output, or octal and hexadecimal if you're using -o.

--common
Print total size of common symbols in each file. When using Berkeley or GNU format
these are included in the bss size.

-t
--totals
Show totals of all objects listed (Berkeley or GNU format mode only).

--target=bfdname
Specify that the object-code format for objfile is bfdname. This option may not be
necessary; size can automatically recognize many formats.

-V
--version
Display the version number of size.

@file
Read command-line options from file. The options read are inserted in place of the
original @file option. If file does not exist, or cannot be read, then the option
will be treated literally, and not removed.

Options in file are separated by whitespace. A whitespace character may be included
in an option by surrounding the entire option in either single or double quotes. Any
character (including a backslash) may be included by prefixing the character to be
included with a backslash. The file may itself contain additional @file options; any
such options will be processed recursively.
