runsvdir(8)                          System Manager's Manual                          runsvdir(8)

NAME
       runsvdir - starts and monitors a collection of runsv(8) processes

SYNOPSIS
       runsvdir [-P] dir [ log ]

DESCRIPTION
       dir  must  be  a directory.  log is a space holder for a readproctitle log, and must be at
       least seven characters long or absent.

       runsvdir starts a runsv(8) process for each subdirectory, or symlink to  a  directory,  in
       the  services directory dir, up to a limit of 1000 subdirectories, and restarts a runsv(8)
       process if it terminates.  runsvdir skips subdirectory names starting with dots.  runsv(8)
       must be in runsvdir's PATH.

       At least every five seconds runsvdir checks whether the time of last modification, the in-
       ode, or the device, of the services directory dir has changed.  If  so,  it  re-scans  the
       service  directory,  and  if it sees a new subdirectory, or new symlink to a directory, in
       dir, it starts a new runsv(8) process; if runsvdir sees a subdirectory being removed  that
       was  previously  there,  it  sends the corresponding runsv(8) process a TERM signal, stops
       monitoring this process, and so does not restart the runsv(8) process if it exits.

       If the log argument is given to runsvdir, all output to standard error  is  redirected  to
       this  log, which is similar to the daemontools' readproctitle log.  To see the most recent
       error messages, use a process-listing tool such as ps(1).  runsvdir writes a  dot  to  the
       readproctitle log every 15 minutes so that old error messages expire.

OPTIONS
       -P     use  setsid(2)  to  run each runsv(8) process in a new session and separate process
              group.

SIGNALS
       If runsvdir receives a TERM signal, it exits with 0 immediately.

       If runsvdir receives a HUP signal, it sends a TERM signal to each runsv(8) process  it  is
       monitoring and then exits with 111.
