how do I stop a running program?
 

I know I can CTL-Z it and then kill the process.
I am asking how to STOP a program in execution.
I know there is a very simple answer but I just cannot recall how to it.

TIA

CTRL-c ?

I do not think you know it, you already wrote it: if you need to kill the process then: the command to kill a process is named kill. See man page. Ctrl-Z will not kill the program, it will stop it. It means the execution is suspended, but can be continued later.

Thanks!
 

Bingo.

Simple does not mean EASY: Try looking this up in the documentation....

Thanks again -- what would we do without the Brits?!

If you know the name of the running process, try; pidof "process". Then, if it returns a pid, you can kill it with kill -9 "pid" or killall "proc name". If pidof return nothing, then either the process is not running or you miss spelled the process name. Use
To see all running processes.
