Hi!, I'm trying to create a script which will ask user for file and checks if it has at least 5 line, if it does than print first and last line. I'm getting following errors Use of uninitialized value $lines in concatenation (.) or string at c:\test\perl\test.pl line 9, <FILE> line 6. Use of uninitialized value $lines in numeric lt (<) at c:\test\perl\test.pl line 14. I will really appreciate your help. You may enlight me if there is different way to do it. Thanks, chiru 

use warnings;
use strict;
print "please enter name of file: ";
chomp($ARGV=<>);
open (FILE, $ARGV) or die "Can't open '$ARGV': $!";
my $lines++ while(<FILE>);

print "\$lines: $lines";
my $last;
my $first = <FILE>;
while (<FILE>) { $last = $_ }
close FILE;
if($lines<5){
print "file must have more than 5 lines";
}
else{

print "\$first: $first";
print "\$last: $last";
}
