qw stands for 'Quote word'. It usually used to create array. Ex. @arr = qw/one two three/; This will create an array with elements one, two and three. Instead of '/' symbol, any other symbol can be used. Ex. @arr = qw #one two three#; @arr = qw %one two three%; If using brackets as symbol, we have the option to use open and closing braces on either end. Ex. @arr = qw [one two three]; or, @arr = qw{one two three}; or, @arr = qw (one two three); Note: Each space considered as seperator for new element.
