Perl Programming/Keywords/chomp

The chomp keyword

chomp is the safer version of chop that removes any trailing strings that corresponds to the current value of $/, which is also known as the $INPUT_RECORD_SEPARATOR in the English module, and returns the total number of characters removed from all arguments. In paragraph mode ($/ = "" ), all trailing newlines from the string are removed. In slurp mode ($/ = undef) or fixed-length record mode ($/ is a reference to an integer or the like) chomp() will not remove anything. If VARIABLE is omitted, it chomps $_. If VARIABLE is a hash, it chomps the values of the hash and not its keys, and resets the each iterator.

Syntax

  chomp VARIABLE
  chomp(LIST)
  chomp
