supervisorctl

Supervisor is a client/server system that allows its users to control a number of processes on UNIX-like operating systems. Supervisorctl is the command-line client piece of the supervisor which provides a shell-like interface.

Start/stop/restart a process:

supervisorctl {{start|stop|restart}} {{process_name}}

Start/stop/restart all processes in a group:

supervisorctl {{start|stop|restart}} {{group_name}}:*

Show last 100 bytes of process stderr:

supervisorctl tail -100 {{process_name}} stderr

Keep displaying stdout of a process:

supervisorctl tail -f {{process_name}} stdout

Reload process config file to add/remove processes as necessary:

supervisorctl update
