Although there are better solutions as has already been suggested above, here is a quick script I just wrote to output 5 lines either side a line number you specify.

Just give it two arguments on the command line when you run it. 1. A line number you want to display, and 2. the file you want to display the line number from.

eg. lnb.pl 14 testfile.txt

This will display lines 9 through to 19 (5 either side of 14) from file testfile.txt

Enjoy!

#!perl

$nmb = shift;
$file = shift;

open (FILE, "<$file") or die $!;
@file = <FILE>;
close FILE;

print "\n";
foreach (@file) {
    if (abs($nmb - ++$i) <= 5) {
        print $i, ":\t$_";
    }
}
print "\n";
