documentation provided for the functions:

This is an alternative to the chop() function. It removes characters at the end of strings corresponding to the $INPUT_LINE_SEPARATOR ($/). It returns the number of characters removed. It can be given a list of strings upon which to perform this operation. When given no arguments, the operation is performed on $_.

This function removes the last character of a string and returns that character. If given a list of arguments, the operation is performed on each one and the last character chopped is returned.

these two functions are very much alike... they both remove one (or more) characters from the end of a string... So how are they different you ask? Chomp() ONLY removes new line characters (these are specified in $/), whereas Chop() removes anything that is at the end of the string (it really doesn't care what it is)...

let's demonstrate these two functions:

#chomp() EXAMPLES $a = "abcdefghij"; chomp($a); print $a; #would return exact string... nothing to remove $a = "abcdefghij\n"; chomp($a); print $a; #would return 'abcdefghij', removed newline $a = "abcdefghij\n"; $b = chomp($a); print $b; #would return 1, it did remove something for sure #chop() EXAMPLES $a = "abcdefghij"; chop($a); print $a; #this would return 'abcdefghi' $a = "abcdefghij"; $b = chop($a); print $b; #this would return 'j'
remember.. this with a little bit of usefulness chop() can be the same as chomp()
$a = "abcdefghij\n"; if ($a =~ /\n$/) { chop $a; } #this could also be \r\n if on windows p +latform
most of the time, you'll want to chomp(), but you might want to use chop() with regexes for the same output

    [Your Mother]: Though a bad match for the OP in question here. :P
    [Corion]: Your Mother: Yeah
    [Your Mother]: Americans are still pumping out video games where you get to slaughter as many Germans as you have the GPU for... It has always struck me as odd that this particular case seems fine to people. :\
    [LanX]: yep heard the same origin story
    [Your Mother]: I like it. I tottered on going into hucksterism because I feel like the world deserves it.
    [LanX]: he ... we have a movement here called Anti-Germans based on this
    [Corion]: Your Mother: I think that's because (in the west) the Nazi-Germans are recognized as universally evil. Of course, you could do some number games to calculate other measures of evil than "historic losers of second world war" to come up with other evils:)
    [Corion]: I've heard "Troll" described as the new Punk, and in a way, it can be as destructive as living the Punk lifestyle, and you don't have to sit out in the cold...
    [LanX]: Anti-Germans
    [LanX]: Socrates was a Troll
