in reply to Executing programs without waiting

exec doesn't return to the "calling" program, so you could fork and exec to get that behaviour.

    Here's what I'm trying now:

    #!/usr/bin/perl

$SIG{CHLD} = "IGNORE";
fork();
exec("perl set");

    Is this right? The first program still doesn't seem to continue until the child program finishes... What am I missing here?

        Ah, that explains it. It's working for me now. Thanks very much!
