system '( nohup sleep 5 ; echo Shell done. ) &';
print "Perl done.\n";

Beware: The message can appear in the middle of the command line. Precede it with a newline to prevent it, but it can still do weird things if you e.g. run mc in the meantime.

    Thanks for the prompt reply.

    I'm just confused as to where the code you provided would be placed in relation to the lines I provided. The two lines I provided both have a Perl script that is executed. Would your code follow my code or does it need to be placed elsewhere?
