How can I see what processes are running on a remote ubuntu server and kill them? [closed]

Question

I started some processes with nohup and they aren't working correctly so I need to find and kill them but I dont know the pid or anything.

Answer 1

SSH in and then use the ps command to list running processes in conjunction with the grep command to filter that result list down to what you need:

ps aux | grep something

"ps aux" returns a list of all processes currently running "grep something" takes that list (via the pipe ("|")) and just outputs strings that match "something".

So for example if you wanted to find the httpd process you could use

ps aux | grep httpd

The results will contain the PID you can use to kill them.

Answer 2

No need for any pipes with pgrep:

pgrep -l httpd
