perldoc -funtie
or more thoroughly perldoc perltie
untie is the way to go if you're dealing with a tied variable...if
you're not then it won't do anything (or at least it shouldn't). The
perltie doc will also hint at the greater range of tie'ing available
above database hashes.

untie or unlink? You had used unlink previously which closed and
deleted a temporary file while close only closes the file which would be
the proper way to terminate a pipe such as used in the solution.

the getpwuid function in scalar context gives you the user of the uid:
[panda]$ perl -le 'print scalar getpwuid($
I don'tknow if this is the best way but I ended up doing this:
my $UID = getpwuid($<);
my @GROUPS = split(" ",`groups $UID`);
Which gets the groups that the user who is running my script belongs
too.
correct me if I am wrong?

Depends on the system.
Have you looked on cpan for a module that does that?
You can always qx() the same way you'd do it
