DaemonTools 中svc命令的使用

The svc program

svc controls services monitored by .

Interface

     svc opts services

opts is a series of getopt-style options. services consists of any number of arguments, each argument naming a directory used by supervise.

svc applies all the options to each service in turn. Here are the options:

• -u: Up. If the service is not running, start it. If the service stops, restart it.
• -d: Down. If the service is running, send it a TERM signal and then a CONT signal. After it stops, do not restart it.
• -o: Once. If the service is not running, start it. Do not restart it if it stops.
• -p: Pause. Send the service a STOP signal.
• -c: Continue. Send the service a CONT signal.
• -h: Hangup. Send the service a HUP signal.
• -a: Alarm. Send the service an ALRM signal.
• -i: Interrupt. Send the service an INT signal.
• -t: Terminate. Send the service a TERM signal.
• -k: Kill. Send the service a KILL signal.
• -x: Exit. supervise will exit as soon as the service is down. If you use this option on a stable system, you're doing something wrong; supervise is designed to run forever.
