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
       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.
