tmp/pids/server.pid contains one line – the process number.
How to get this line and assign this value to a variable?
In the end, you just need to kill the process with
kill -9 .
$ pid=$(cat /var/run/sshd.pid) $ echo $pid 3528
if you just need to kill the process, then you can do it without a variable:
kill -9 $(cat /var/run/sshd.pid)
