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
       exits. 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/super-
       vise,  which  must  be  writable to supervise.  The status information can be read by svs-
       tat(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 run-
       ning, 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 reli-
       ably start a collection of supervise processes.
