> Missing semicolon. It's not missing. PP is making a point about "single-command variables."

  Single-command environment variables, to be precise. The same thing that gets created when you use "export", but isn't created when you use "=" on a line on its own: $ FOO=BAR env | grep FOO # Exists as an environment variable passed to env FOO=BAR $ env | grep FOO # But only for that command $ FOO=BAR # Creates a variable (not an environment variable) $ env | grep FOO # As shown by not being passed down $ echo $FOO # But still accessible in this context BAR $ export FOO=BAR # Promotes it to an environment variable (the "=BAR" is optional since it's already defined) $ env | grep FOO # And as such is now visibly passed down FOO=BAR (Yes, bash does mix these together so it's easy to accidentally replace something you don't intend to)
