Use $. to determine the current file line number. I don't do command line, but the following should point you in the right direction:
use strict;
use warnings;
my $tempFileName = 'temp.txt';
open tempFile, '>', $tempFileName;
print tempFile <<TEMP;
Line one
Line two
Line three
Line four
Line five
TEMP
close tempFile;
open tempFile, '<', $tempFileName;
while (<tempFile>) {
print "$_" if $. >= 2 && $. <= 4;
}
close tempFile;
Prints:
Line two
Line three
Line four
