supervise(8)                                         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/supervise, 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  super-
       vise  is already running in s.  Once supervise is success-
       fully 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 pro-
       cesses.
