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.
