Bash Jobs and Processes Finding information about a running process
Example
ps aux | grep <search-term> shows processes matching search-term
Example:
root@server7:~# ps aux | grep nginx
root 315 0.0 0.3 144392 1020 ? Ss May28 0:00 nginx: master process /usr/sbin/nginx
www-data 5647 0.0 1.1 145124 3048 ? S Jul18 2:53 nginx: worker process
www-data 5648 0.0 0.1 144392 376 ? S Jul18 0:00 nginx: cache manager process
root 13134 0.0 0.3 4960 920 pts/0 S+ 14:33 0:00 grep --color=auto nginx
root@server7:~#
Here, second column is the process id. For example, if you want to kill the nginx process, you can use the command kill 5647. It is always adviced to use the kill command with SIGTERM rather than SIGKILL.
