TIMTOWTDI:

if (fork==0) { exec qw{t1.pl arg1 arg2 arg3}; }
This will fork the program and start your command in the child process (where fork returns 0).
Sorry if my advice was wrong.

    This TIMTOWTDI is probably better than the other WTDI. But I'd like to make it clear to the OP that exec() takes a list, so therefore:

    exec 't1.pl', $arg1, $arg2, $arg3;

    (Well, better in the sense that I cringe whenever something goes through sh -c when not absolutely necessary. It is very easy to introduce a bug that way.)
