Anyway, this is how I can see that Solaris 10 /usr/xpg4/bin/sh is really just a Korn shell in disguise (maybe compiled with some switches to turn off Korn extensions and enhance Bourne-compatibility): $ strings /usr/xpg4/bin/sh | grep '@(#)' @(#)Version M-11/16/88i $ strings /bin/ksh | grep '@(#)' @(#)Version M-11/16/88i Maybe you can do something like: $ strings /bin/sh | egrep '@.*#|Version' $ strings /bin/ksh | egrep '@.*#|Version' and see which the outputs are, and what they suggest. Or use the trick explained here: <http://unix.ittoolbox.com/groups/technical-functional/shellscript-l/command-to-find-the-version-of-ksh-1490264> which reads: """ To get the Ctrl-V function to work, you need to be in "vi" mode. To do this, type in the following: $ set -o vi Now simply press and release the "Esc" key one time, then perform a Ctrl-V (you have to press and hold the Ctrl key, then press and release the v key. Release both keys when you've done this). On Solaris 8 & 10, you should see the following: $ Version M-11/16/88i """ (Disclaimer: the above suggestions are mostly wild guesses, as I have absolutely no experience with OSF1/Tru64). > > Do you happen to have bash installed on your system? > Yes.
