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  super-
       vise.

       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.
