    exec()

    Hmmm...

    I wonder, since exec() run as the user "nobody" how can I get it to do things that I in shell only can do as myself.

    Shellscript? (I used UNIX tcsh-script 5 years ago... not since then).

    Possibly using su? There could be a security problem there though - maybe if you created a shell script which contained the su command.

    How do I use "su"?

    If I execute it in the shell I get a question for password. That is good, but how do I answer it from a script?

    I would presume there is a command-line option to pass the password on the command. Try a Google search.

    Well, the "man" (man su) or the search for su(1) gives the answere that this is the proper synopsis.

    su [options] [username] [arguments]

    Anyone who knows if I can pass the password along in the arguments?

    I tried "-c"-option, but that just passed it on to the first prompt appearing after the password prompt.
