Hello again,

I have a shell script that I am converting to Perl which is used in my Perl/Tk application. It's such a simple script, that I have wasted hours failing clearly lists me for the Darwin awards. I need to check if a user is root, and if not, list that he needs root privileges before continuing. What I have that does not work is:

my $user = `whoami`;
my $uid = getpwnam("$user"); # this is not working as I would expect
if ("$uid" != 0)
{
   print "You must be root Ian! You obtuse moron!!!\n);
}

My god this is so simple in shell script, how can I be screwing it up so badly???

Thanks for any thoughts!

Ian

Sorry, to explain, it is the UID of the user.
