chomp - remove a trailing record separator from a string
chomp VARIABLE
chomp LIST
chomp
This is a slightly safer version of chop. It removes any line ending that corresponds to the current value of $/
(also known as $INPUT_RECORD_SEPARATOR
in the English
module). It returns the total number of characters removed from all its
arguments. It's often used to remove the newline from the end of an input
record when you're worried that the final record may be missing its
newline. When in paragraph mode ($/ = ""
), it removes all trailing newlines from the string. If
VARIABLE is omitted, it chomps $_
. Example:
while (<>) { chomp; # avoid \n on last field @array = split(/:/); # ... }
You can actually chomp anything that's an lvalue, including an assignment:
chomp($cwd = `pwd`); chomp($answer = <STDIN>);
If you chomp a list, each element is chomped, and the total number of characters removed is returned.
