Kill a process by command
 

What is the syntax for killing a command using the command that was run such as (cp)?

kill ???

Thanks!

killall whatever

Sometimes this doesn't work, though, in which case it's good to use the process ID number. You can usually find that out by running:

ps ax

There are other related commands for killing processes (sometimes they won't accept the killall command) - but I haven't figured 'em out yet.

Besides, when you've a process running in a window-defined GUI environment, you can use the console and type in : XKILL
Then you'll just have to point and click with your mouse on the window running the process you want to kill.

No GUI command line only.

Thanks for your input.
