Aha. Thanks for that. At least we get diversity in our shells. I quite like that, it reminds me of the UNIX days when every OS was slightly different at the shell level, with different command line options for simple commands in Solaris/IRIX/HP-UX and those myriad of different IBM systems. Can't have it too easy, can we? Or else anyone would be able to do our programmer jobs!
