Re^3: Forking an operative terminal

You can get rid of the defunct processes by setting $SIG{CHLD} = 'IGNORE' in the parent. Also, you should use sh -c instead of bash -c in "bash -c '$command; bash'", since only sh is guaranteed to exist.

And the user's shell can be found with this piece of code:

my ($shell, $uid);
while (($uid, $shell) = (getpwent)[2,8]) {
    last if $uid == $<;
}
say $shell;

Fine, I was trying to place an 'exit' into the exec to solve the problem, but the signal handler worked perfectly and sent the zombies back to their niches. As well as the code for user shell determination. Thanks again, your Wisdom. I also want to apologize because now I realize that my question concerned the shell and OS, not perl.
