Commands I learned while trying to make supervisord work on my CentOS machine.
Before this i knew only grep and ps command with aux parameters.
What I did was:
ps aux | grep supervisor
see the pid of process and then
kill 23467
More interesting way:
kill -HUP `pgrep superv`
Explanation:
kill -HUP
sends hang-up signal to the selected process.
HUP usually restarts the process.
pgrep looks through the currently running processes and lists the process IDs which matches the selection criteria to stdout.
And then this command:
pkill process_name
to kill based on process name or send any signal
pkill -HUP superv
