thank you - using your example, I have the following 
#! / usr/bin/perl -w

use strict;
use warnings;

use POSIX 'strftime';

my $nm = strftime('%Y', localtime).".txt";

my $filename = 'Facs_Data.txt';
open my $fh, '<', $filename
    or die "Couldn't open '$filename': $!";

my @lines = map  { /:([^\s]+)/ ? $1 : () } # take the stuff between th
+e : and the first blank
            grep { /Acct:/ } <$fh>; # Read a file line by line and sel
+ect the lines matching Acct:
        my $outfile = $_."_"."$nm" for @lines ;
        print $outfile;
        #open (OUTFILE, ">$outfile");
# do whatever with the values in @lines
#print "$_\n" for @lines;
close($filename);

root@localhost:~/GoldenLFiles# perl facs.pl Use of uninitialized value $outfile in print at facs.pl line 17, <$fh> line 168801.

If I comment the print $outfile to see the output I get the error above. What am I missing here? Thanks in advance
