Does the opposite of a
shift(). Or the opposite of a
push(), depending on how you look at it. Prepends list to the front of the array, and returns the new number of elements in the array.
unshift(ARGV, '-e') unless $ARGV =~ /^-/;
Note the LIST is prepended whole, not one element at a time, so the prepended elements stay in the same order. Use
reverse() to do the reverse.
