runsvdir(8)                                                        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 inode, 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.
