  It boggles my mind that people use a language where x = 0 doesn't work and x=$y is a security flaw

    Sometimes it's easier to use tools you know will be available than to ensure your tool of choice will be available everywhere you need it to be. JavaScript, esp. pre v6, is another example that makes almost no sense when you ignore its ubiquity

    > x = 0 doesn't work Maybe it's just me, but I love how the assignment syntax can be used just for a single command: 'MANPAGER=cat man' is a lot nicer than '(MANPAGER = cat; man)'. > and x=$y is a security flaw When is variable assignment a security flaw?

      if $y is untrusted input then you need to quote it or you've introduced shell injection attack to the script.

        You don't need to quote variables on the right hand side of an assignment.
