Joy. :-( There are other hacky ways of trying this out - try "type ls" to see if type works, then fall back to which, etc. Or actually try running the extractor command (xzcat /dev/null), and check for the return code. But those are all hacky solutions. Maybe better to just detect posh and bail with a message "get a real shell", then... -- Steve McIntyre, Cambridge, UK. st...@einval.com Google-bait: http://www.debian.org/CD/free-linux-cd Debian does NOT ship free CDs.
