How do I stop a process or command that's running in the background?

The commands described below need to be entered while logged in to the Unix server.   Normally you'll see a prompt ending with $ when the command interpreter (or shell) is ready for another command.

Issue the command :-

ps -fu username

(where username is your own username, such as ano23) to see which other processes you have running.  For example:

ps -fu ano23

Then, find the process number (PID) of the process (on the second column of the output from the ps command), and give the command

kill -9 pid

where pid is the process number for the command you want to stop.
