Follows version that makes PATH case-insensitive. Works even if you
have several environment variables that match /^path$/ (possible under
Linux et. al.) their content is printed one after another).

ruby -e 'ENV.keys.grep(/^path$/i).each { |x| puts ENV[x].split(File::PATH_SEPARATOR)}'

Terrorism is the systematic use of violence and brutality as a means of
gaining some political end. So the "War on Terrorism" is a failure if
it increases violence and brutality and even may be terrorism by itself
if some well-known incidents turn out not to be singular ones.      :-|
