Hey,

i am new to Linux and might need some help.

I ran a shell script which copys data to a directory.
Since there is a mistake in the shell script I want to stop the process.

I tried ctrl + c, ctrl + z, restarting linux.

screen -ls does not list any screen, job does not give any output either...

Hi brrixx, Welcome to LinuxQuestions!

Check out the command ps:
It'll give you more info than you need!

will give you a list of all running processes and their PIDs.

will give you a dynamically updated list of processes which may also be useful to you.

Does the shell script run in the foreground? I.e., do you get a shell prompt after you launch the script? If so, control-C should normally interrupt it. There may be situations, when the system is very busy, that the key combination control-C is not processed immediately, or not at all.

If you can launch another shell, for example in a different window, list your processes and find which process corresponds to the script. You can also use commands like top to identify processes that use the CPU a lot. Most likely, the process(es) that you want to terminate are among those.
What happened when you did this? Are you saying that restarting Linux did not kill the process?
I am not aware of a command named job. There is a command named jobs, which lists the running and stopped jobs of the shell that calls it.

I don't understand what screen has to do with your question.

To build on what Soadyheid's excellent suggestion, also see man kill and man killall.

The bash shell also contains these built-in commands: jobs, fg, bg. Also nice, renice.

You can launch any command "in the background" by adding a "!" at the end of the command-line.

All of these are considered children of your shell process, and therefore will be terminated if you log out.

Actually that is an ampersand at the end of the line ("&").
