    To be clear.

    Programing Perl describes chomp as "This function (normally) deletes a trailing newline from the end of a string contained in a variable. This is a slightly safer version of chop"

    chop itself is "This function chops off the last character of a string variable and returns the character chopped."

    IOW, chop does what it means, it chops off the end. chomp is a very similar one, that only (before version 5.6) chops off ^M

      Actually, chomp, by default, removes a newline. Which is actually ^J, not ^M. ^M is a carriage return, and will be left alone by chomp (unless $/ is set to something that contains it).

        Excellent point. But chojp doesn't sound like Larry's native tongue. And there that little known factual fauxism that Larry originally wrote perl for the typewriter.

    I know Larry visits Australia from time to time, and he probably ate what is possibly the best flavour to dollar ratio chocolate bar in the world, the Cadbury Chomp.


    I assume he named the chomp operator in honour.

    chomp removes newlines. Which, if $/ isn't set, is ^J, not ^M, which will be left alone by chomp.

      Are you making fun of me?
