If service doesn?t start with a dot or slash, +it is searched in the default services directory /var/service/, otherwise +relative to the current directory. + +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. + +The sv program can be sym-linked to /etc/init.d/ to provide an LSB init +script interface. The service to be controlled then is specified by the +base name of the "init script". + +status + Report the current status of the service, and the appendant log service + if available, to standard output. +up + If the service is not running, start it. If the service stops, restart it. +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. +once + If the service is not running, start it. Do not restart it if it stops. +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. +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, 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, + runsv(8) exits. This command is ignored if it is given to an appendant + log service. + +sv actually looks only at the first character of above commands. + +status + Same as status. +start + Same as up, but wait up to 7 seconds for the command to take effect. + Then report the status or timeout. If the script ./check exists in + the service directory, sv runs this script to check whether the service + is up and available; it's considered to be available if ./check exits + with 0. +stop + Same as down, but wait up to 7 seconds for the service to become down. + Then report the status or timeout. +restart + Send the commands term, cont, and up to the service, and wait up to + 7 seconds for the service to restart. Then report the status or timeout. + If the script ./check exists in the service directory, sv runs this script + to check whether the service is up and available again; it's considered + to be available if ./check exits with 0. +shutdown + Same as exit, but wait up to 7 seconds for the runsv(8) process + to terminate. Then report the status or timeout. +force-stop + Same as down, but wait up to 7 seconds for the service to become down. + Then report the status, and on timeout send the service the kill command. +force-reload + Send the service the term and cont commands, and wait up to + 7 seconds for the service to restart. Then report the status, + and on timeout send the service the kill command. +force-restart + Send the service the term, cont and up commands, and wait up to + 7 seconds for the service to restart. Then report the status, and + on timeout send the service the kill command. If the script ./check + exists in the service directory, sv runs this script to check whether + the service is up and available again; it?s considered to be available + if ./check exits with 0. +force-shutdown + Same as exit, but wait up to 7 seconds for the runsv(8) process to + terminate. Then report the status, and on timeout send the service + the kill command. + +Additional Commands + +check + Check for the service to be in the state that's been requested. Wait up to + 7 seconds for the service to reach the requested state, then report + the status or timeout. If the requested state of the service is up, + and the script ./check exists in the service directory, sv runs + this script to check whether the service is up and running; + it's considered to be up if ./check exits with 0. + +Options + +-v + wait up to 7 seconds for the command to take effect. + Then report the status or timeout. +-w sec + Override the default timeout of 7 seconds with sec seconds. Implies -v. + +Environment + +SVDIR + The environment variable $SVDIR overrides the default services directory + /var/service. +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. + +Exit Codes + sv exits 0, if the command was successfully sent to all services, and, + if it was told to wait, the command has taken effect to all services. + + For each service that caused an error (e.g. the directory is not + controlled by a runsv(8) process, or sv timed out while waiting), + sv increases the exit code by one and exits non zero. The maximum + is 99. sv exits 100 on error. +*/ + /* Busyboxed by Denis Vlasenko <vda.linux@googlemail.com> */ /* TODO: depends on runit_lib.c - review and reduce/eliminate */ |
