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



NAME
       supervise - starts and monitors a service.

SYNOPSIS
       supervise s

DESCRIPTION
       supervise  switches to the directory named s and starts ./run. It restarts ./run if ./run ex‐
       its. It pauses for a second after starting ./run, so that it does not  loop  too  quickly  if
       ./run exits immediately.

       If  the file s/down exists, supervise does not start ./run immediately. You can use svc(8) to
       start ./run and to give other commands to supervise.

       supervise maintains status information in a binary format inside the  directory  s/supervise,
       which must be writable to supervise.  The status information can be read by svstat(8).

       supervise  may exit immediately after startup if it cannot find the files it needs in s or if
       another copy of supervise is already running in s.  Once supervise is  successfully  running,
       it  will  not  exit unless it is killed or specifically asked to exit. You can use svok(8) to
       check whether supervise is successfully running. You can use svscan(8) to  reliably  start  a
       collection of supervise processes.
