SYNOPSIS

       sv [-v] [-w sec] command services

       /etc/init.d/service [-w sec] command

DESCRIPTION

       The  sv  program  reports  the current status and controls the state of
       services monitored by the runsv(8) supervisor.

       services consists of one or more  arguments,  each  argument  naming  a
       directory  service  used  by runsv(8).  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,  shut-
       down, 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''.

COMMANDS

       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 com-
              mand is ignored if it is given to an appendant log service.

       sv actually looks only at the first character of these commands.

   Commands compatible to LSB init script actions
       status Same as status.

              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 con-
              sidered 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 ser-
              vice  is  up  and  running;  it's considered to be up if ./check
              exits with 0.

OPTIONS

       -v     If the command is up, down, term, once, cont, or exit, then 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.
              This option 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
       if the service is down, and 4 if the status is unknown.  It exits 2  on
       wrong usage, and 151 on error.
