Add the following to your script:

use Data::Dumper;

...and then on the line immediately preceding your "for" loop, add, "print Dumper \@array;".

There might be something broken in your input data, and that would be a simple means of identifying (or eliminating) it as a problem.

    Done and here is a sample of what I got back:
    ', 'sn: ThisUser ', 'mail: ', 'cn: This User ', 'uid: MyUID
    Now what?

      Well, that does tell us that you're not chomping the input, which you should be doing. chomp @array; would take care of that problem. What it doesn't show me is how the following would fail:

      my @array = ( 'sn ThisUser', 'mail:', 'cn: This User', 'uid: MyUID', ); foreach my $line ( @array ) { if( $line =~ m/^mail:\s+([\S]+)/ ) { print "$1\n"; } }

      It doesn't fail on my system, which leads me to believe that the problem is in a portion of your code that we're not seeing, or in your data-set. If your data-set looks clean, we're back to the portion of the code that we haven't been shown.


        Thank you for your time Dave in going to this much effort to help a total stranger. Not sure exactly what fixed it, but I used the chomp as recommended and then copied/pasted your code and that seems to have solved the issue.

        Thanks again and have a great Christmas!
