Chop and chomp in perl
Just a reminder, so I remember the difference! - chomp is a safer version of "chop" removes any trailing string that matches what perl thinks is a new line)
$string = "abcdef";
chop($string) # $s is now f, $string is now abcde
chomp($string) # $string is still now abcde
$string = "abcdef\n";
chomp($string) # $string is now abcdef
