if (my $username = getpwuid($input_uid)) {
print "Founf the user $username\n";
} else {
print "No user found\n";
}

Subject: Test if string does not exist in an array.
Apologies if this is a bit noobie, but I have been left with a short
window to write a tool and I have had no experience with Perl. Very
familiar with Kornshell, and so far my Perl script is going okay.
However, I am struggling to get a test working correctly. Is there a
simple way to test if a string does not exist in an array?
I am trying to test if some user input (a userid) is valid and error
if it does not exist. Currently have the contents of /etc/passwd in an
array, and can test for valid users, but all my efforts to test for
invalid have failed miserably.
I am on AIX, not sure on the Perl version.
Current test for valid is :
return 1 if (grep(/$user/,$udata));
Any help would be much appreciated.
Ashley
