Delete file after script terminated

Question

I was asking myself if it is possible that when I terminate a bash script with crtl+c, the script would execute a last command before aborting, like delete a file which was created by that script?

Answer 1

You can trap the pseudo-signal EXIT to execute something before exiting for any reason:

trap 'rm myfile' EXIT

or trap INT to excecute a command on before exiting due to Control-C:

trap 'rm myfile' INT
