Built-In Functions Chop

The chop() function removes the last character of each item

Scalar context

$foo = "Hello\n";
chop( $foo );
# $foo is now "Hello"

List context

@foo = ( "Goodbye\n", "cruell", "world\n" );
chop( @foo );
# @foo is now ( "Goodbye", "cruel", "world" )

Notice chop can remove more than simply "\n" characters!
