Hi dude,
the actual problem is the wrong "if"-statement, one line before the "groupdel" command.
Due to the exclamation mark, it reads like "If the group ... is NOT found, delete it",
but since the group does exist, the else part of that if statement gets triggered.
So you got to remove the exclamation mark (!) in the line 53.

I guess that happened because you copied it from the groupadd section.

Here are some further suggestions:

1. imho you don't need to read from STDIN at the program start, so try this instead:

Code:

my ($group_name, $group_id, $user_name, $user_id, $choice);

2. There is a "-g" option missing between the groupadd command and $group_id

3. groupdel requires groupname as argument, so probably you should remove -g $group_id (see jim's answer)

4. you should not simply system("some-command") and then independently print some status or return code. Try this:

Code:

system ("/usr/sbin/groupadd -g $group_id $group_name && echo 'Success!' || echo 'Error!'");

5. if ($choice == 1) ... elsif ($choice == 2) ... if ($choice == 3) seems not to be consistent

6. If your perl script still misbehaves, consider using the perl debugger: perl -d yourscript.pl

HTH, good luck!

NOTES

       The  groupdel utility only deletes a group definition that is in the local /etc/group file. If a network nameservice such as NIS or NIS+ is
       being used to supplement the local /etc/group file with additional entries, groupdel cannot change  information	supplied  by  the  network
       nameservice.
