NAME
runsvctrl - controls a service monitored by runsv(8).
SYNOPSIS
runsvctrl command services
DESCRIPTION
services consists of one or more arguments, each argument naming a directory used by runsv(8). command is one of up, down, once, pause, cont, hup, alarm, interrupt, 1, 2, term, kill, or exit.
For each service of services, runsvctrl sends the command command to the service, which must be controlled by runsv(8).
COMMANDS
- up
-
If the service is not running, start it. If the service stops, restart it.
- down
-
If the service is running, send it a TERM signal. If ./run exits, start ./finish if it exists. After it stops, do not restart service.
- once
-
If the service is not running, start it. Do not restart it if it stops.
- pause
-
If the service is running, send it a STOP signal.
- cont
-
If the service is running, send it a CONT signal.
- hup
-
If the service is running, send it a HUP signal.
- alarm
-
If the service is running, send it a ALRM signal.
- interrupt
-
If the service is running, send it a INT signal.
- quit

- 1
-
User-defined 1. If the service is running, send it a USR1 signal.
- 2
-
User-defined 2. If the service is running, send it a USR2 signal.
- term
-
If the service is running, send it a TERM signal.
- kill
-
If the service is running, send it a KILL signal.
- exit
-
If the service is running, send it a TERM signal. Do not restart the service. If the service is down, and no log service exists, runsv(8) exits. If the service is down and a log service exists, send a TERM signal to the log service. If the log service is down, runsv(8) exits. This command is ignored if it is given to service/log/supervise/control.
runsvctrl actually looks only at the first character of command.
EXIT CODES
runsvctrl exits 0, if the command was sent successfully to all services.
For each service that caused an error (e.g. the directory is not controlled by a runsv(8) process), runsvctrl increases the exit code by one and exits non zero. The maximum is 100.
runsvctrl exits 111 on error.
