runsv (8) +.SH SYNOPSIS +.B sv +[\-v] [\-w +.I sec\fR] +.I command +.I services +.P +.BI /etc/init.d/ service +[\-w +.I sec\fR] +.I command +.SH DESCRIPTION +The +.B sv +program reports the current status and controls the state of services +monitored by the +.BR runsv (8) +supervisor. +.P +.I services +consists of one or more arguments, each argument naming a directory +.I service +used by +.BR runsv (8). +If +.I service +doesn't start with a dot or slash, it is searched in the default services +directory +.IR /var/service/ , +otherwise relative to the current directory. +.P +.I command +is one of up, down, status, once, pause, cont, hup, alarm, interrupt, 1, 2, +term, kill, or exit, or start, stop, restart, shutdown, force-stop, +force-reload, force-restart, force-shutdown. +.P +The +.B sv +program can be sym-linked to +.I /etc/init.d/ +to provide an LSB init script interface. +The +.I service +to be controlled then is specified by the base name of the ``init script''. +.SH COMMANDS +.TP +.B status +Report the current status of the service to standard output. +.TP +.B up +If the service is not running, start it. +If the service stops, restart it. +.TP +.B down +If the service is running, send it the TERM signal, and the CONT signal. +If ./run exits, start ./finish if it exists. +After it stops, do not restart service. +.TP +.B once +If the service is not running, start it. +Do not restart it if it stops. +.TP +.B pause cont hup alarm interrupt quit 1 2 term kill +If the service is running, send it the STOP, CONT, HUP, ALRM, INT, QUIT, +USR1, USR2, TERM, or KILL signal respectively. +.TP +.B exit +If the service is running, send it the TERM signal, and the CONT signal. +Do not restart the service. +If the service is down, and no log service exists, +.BR runsv (8) +exits. +If the service is down and a log service exists, send the TERM signal to the +log service. +If the log service is down, +.BR runsv (8) +exits. +This command is ignored if it is given to an appendant log service. +.P +.BR sv +actually looks only at the first character of these +.IR command s. +.SH COMMANDS compatible to LSB init script actions +.TP +.B status +Same as +.IR status . +.TP +.B start +Same as +.IR up , +but wait up to 7 seconds for the command to take effect. +Then report the status or timeout. +.TP +.B stop +Same as +.IR down , +but wait up to 7 seconds for the service to become down. +Then report the status or timeout. +.TP +.B restart +Send the commands +.IR term , +.IR cont , +and +.I up +to the service, and wait up to 7 seconds for the service to restart. +Then report the status or timeout. +.TP +.B shutdown +Same as +.IR exit , +but wait up to 7 seconds for the +.BR runsv (8) +process to terminate. +Then report the status or timeout. +.TP +.B force-stop +Same as +.IR down , +but wait up to 7 seconds for the service to become down. +Then report the status, and on timeout send the service the +.I kill +command. +.TP +.B force-reload +Send the service the +.I term +and +.I cont +commands, and wait up to 7 seconds for the service to restart. +Then report the status, and on timeout send the service the +.I kill +command. +.TP +.B force-restart +Send the service the +.IR term , +.I cont +and +.I up +commands, and wait up to 7 seconds for the service to restart. +Then report the status, and on timeout send the service the +.I kill +command. +.TP +.B force-shutdown +Same as +.IR exit , +but wait up to 7 seconds for the +.BR runsv (8) +process to terminate. +Then report the status, and on timeout send the service the +.I kill +command. +.SH OPTIONS +.TP +.B \-v +If the +.I command +is up, down, term, once, or exit, then wait up to 7 seconds for the command +to take effect. +Then report the status or timeout. +.TP +.B \-w \fIsec +Override the default timeout of 7 seconds with +.I sec +seconds. +This option implies +.IR \-v . +.SH ENVIRONMENT +.TP +.B SVDIR +The environment variable $SVDIR overrides the default services directory +.IR /var/service/ . +.TP +.B SVWAIT +The environment variable $SVWAIT overrides the default 7 seconds to wait +for a command to take effect. +It is overridden by the \-w option. +.SH EXIT CODES +.B sv +exits 0, if the +.I command +was successfully sent to all +.IR services , +and, if it was told to wait, the +.I command +has taken effect to all services. +.P +For each +.I service +that caused an error (e.g. the directory is not controlled by a +.BR runsv (8) +process, or +.B sv +timed out while waiting), +.B sv +increases the exit code by one and exits non zero. +The maximum is 99. +.B sv +exits 100 on error. +.P +If +.B sv +is called with a base name other than +.BR sv , +it exits 1 on timeout or trouble sending the command. +If the +.I command +is +.BR status , +it exits 3 if the service is down, and 4 if the status is unknown. +It exits 2 on wrong usage, and 151 on error. +.SH SEE ALSO +runsv(8), +runsvdir(8), +runsvchdir(8), +chpst(8), +svlogd(8), +runit(8), +runit-init(8)
