I meant "free speech" and not "free beer". Ksh is still not free speech software.

Even in the proprietary unix world the use of /bin/ksh is drastically being reduced. Most vendors are moving to /bin/sh for scripts. Obviously going from /bin/ksh to /bin/sh is pretty trivial as posix sh is based on ksh88. But there are still a few vendors that cling to /bin/csh scripts. There is no explaining it. Bob
