Synopsis

svc [ -+=Ll12udopchaitkwxq ] services

Description

services consists of any number of arguments, each argument naming a directory used by supervise(8) .

svc applies all the options to each service in turn.

Options

-=
Send all subsequent signals to the parent process instead of its process group. This is the default.
-+
Send all subsequent signals to the entire process group instead of just the parent process.
-L
Send all subsequent signals to the running log process, if it exists.
-l
(default) Send all subsequent signals to the main process. This may be useful for controlling both a log and main process in one shot or avoiding race conditions after using -L.
-u
Up. If the service is not running, start it. If the service stops, restart it.
-d
Down. If the service is running, send it a TERM signal and then a CONT signal. After it stops, do not restart it.
-o
Once. If the service is not running, start it. Do not restart it if it stops.
-p
Pause. Send the service a STOP signal.
-c
Continue. Send the service a CONT signal.
-h
Hangup. Send the service a HUP signal.
-a
Alarm. Send the service an ALRM signal.
-i
Interrupt. Send the service an INT signal.
-t
Terminate. Send the service a TERM signal.
-k
Kill. Send the service a KILL signal.
-q
Quit. Send the service a QUIT signal.
-1
User 1. Send the service a USR1 signal.
-2
User 2. Send the service a USR2 signal.
-w
Window resize. Send the service a WINCH signal.
-x
Exit. supervise(8) will exit as soon as the service is down. If you use this option on a stable system, you’re doing something wrong; supervise(8) is designed to run forever.

Environment

SUPERVISEDIR
If set, the named directory is used instead of supervise for the status information and control files. If $SUPERVISEDIR is an absolute path, it is suffixed with the path to s with all slashes ("/") replaced with colons (":").
