Thanks a lot. After looking around I also found async-shell-command and
shell-command. Am I right in assuming that, as the script is not
producing any output, these commands are equivalent?

In addition, when using async-shell-command I get asked "A command is
running. Kill it? (yes or no)"
Is there any way to avoid this?

Cheers,

Rainer
