To start with, perl exec is not going to return control to the calling program.

perldoc -f exec exec LIST exec PROGRAM LIST The "exec" function executes a system command and never returns-- use "system" instead of "exec" if you want it to return. It fails and returns false only if the command does not exist and it is executed directly instead of via your system's command shell (see below).

To spawn another process is quite easy in Perl. The following code will do what you want:
... my $pid = fork(); if (undefined $pid) { die 'Fork failed'; } if (!$pid) { # I am in the child process system $MYCOMMAND; exit; } # I am in the parent process # continue with other business ...
