You need to fork a new process.
if ($pid = fork) {
print "child ($pid) is doing his own thing.\n";
exit;
}
elsif (defined $pid) {
# I'm the child
exec "someprocess", @args;
die "couldn't exec someprocess @args: $!";
}
else {
die "fork failed: $!";
}
The exec() function replaces the current process with a new one, so the
die "couldn't exec..." line should only be reached if exec() fails.
For more, check up on:
perldoc -f fork
perldoc -f exec
