Solaris /bin/sh was a real real dumb version of the bourne shell. Solaris included /bin/ksh as part of the core distribution (ksh88 was a part of the SVr4 specification) and so many scripts were written with #!/bin/ksh at the start (including tools like "patchadd"). Note Solaris had bugs in those tools because they didn't start "#!/bin/ksh -p" so if you had a $ENVFILE that included lines like "set -o noclobber" or had aliases then scripts would break (patchadd was a perfect example). Many of these got fixed by Solaris 8 :-) -- rgds Stephen
