chomp VARIABLE
chomp LIST
chomp
This is a slightly safer version of chop (see below). It removes any
line ending that corresponds to the current value of $/ (also known as
$INPUT_RECORD_SEPARATOR in the English module). It returns the number
of characters removed. It's often used to remove the newline from the
end of an input record when you're worried that the final record may be
missing its newline. When in paragraph mode ($/ = ""), 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.
