svwaitdown - waits for services controlled by supervise(8) to be down
svwaitdown [ -v ] [ -k ] [ -t sec ] services
services consists
of one or more arguments. Each service directory must start with a slash.
svwaitdown sends each service given at the command line the ``down'' command,
and waits for it to become down. The services given at the command line
must be controlled by supervise(8).
svwaitdown blocks, limited by a timeout,
until all services are down or reports errors.
- -v
- verbose. Print verbose
messages to stderr.
- -t sec
- Set the timeout for waiting for services to become
down to sec seconds. sec must be between 2 and 6000. Default is 600 (10 minutes).
- -k
- Kill. If the timeout is reached before all services are down, tell the
supervise(8) processes to send the services a KILL signal.
- -x
- Exit. Send each
service the ``exit'' command additionally to the ``down'' command, and wait for
the corresponding runsv(8) processes to exit instead for the services to
be down. This option should only be used by runit(8) in stage 3 when runsvdir(8)
is already stopped.
svwaitdown returns 0 as soon as all services
are down.
If a service is usually controlled by supervise(8), but no supervise(8)
process is currently running, svwaitdown treats this service as if it would
be down.
For each service that causes an error while checking, svwaitdown
increases the exit code by one and exits non zero. The maximum is 100.
svwaitdown
returns 111 if the timeout sec was reached.
