Ingore this article if you don't use the User Agent (UA) on your UNIXPC. When using "!command" to invoke commands from UA windows, it seems that UA fork/exec's /usr/lib/ua/uasetx, passing the parameters "/bin/sh -c command". Uasetx, in turn, seems to fork/exec the shell (first parameter) to invoke the command. And the shell, in turn, fork/exec's the command. UA ignores the $SHELL environment variable when invoking uasetx. And uasetx ingores $SHELL. If command is a ksh alias, you lose. Am I missing something here? Is there any way to coerce UA into using ksh instead? To circumvent this problem, I used bpe to zap the appropriate constant "/bin/sh" to "/bin/ks" in /usr/bin/ua, and I "ln /bin/ksh /bin/ks". Works fine -- UA now uses ksh to invoke !commands, and alias' work. I am running 3.5.1.4 (?), but the correct "/bin/sh" is just past the message "You must be an expert to execute shell commands". Probably the same in 3.51. Anybody: Is there an easier way? If not, I hope this helps.... -- "People will do anything for a potato" {amdahl, mtxinu, pacbell, sun}!rtech!gusano!ralph ralph%gusano@rtech.com

I just moved /bin/sh and linked /bin/ksh as /bin/sh. Seriously, I have yet to find one thing that *doesn't* work because of this. Rob Stampfli att!cbnews!res (work) osu-cis!n8emr!kd8wk!res (home)

I've tried this on every OS that AT&T has sent out including 2.0, 3.0, 3.5, 3.5.1.4, 3.51. I haven't tried it on 3.51a. I've run for almost a year this way. The biggest problems relate to the history files. It seems that certain programs, including /usr/bin/Instcpio.sh, among others, don't work properly. Usually this seems to be related to the .kshistory files not being readable (or writable). Also, it'll run .kshrc every time UA tries to run something. I include things to run sysinfo (thanks, lenny), and these always get executed even for simple stuff like 'Change passwd'. Also, when I use the 'p' flag in the Office, things didn't work right, but then again, even now, whenever I open a window with 'p', the g----mn .kshistory gets owned by root with 600 perms. This messes up my next non-p shell. I think I also had severe problems with ph dying all the time. After much frustration, I have switched back to sh. Has anyone tried this with 3.51a? I'd sure like to run ksh instead of sh, but I'm no longer willing to try this. I know someone who has been running ksh for at least a year now as /bin/sh and he says it's no problem.

So far I have had no problems although I haven't conciously tried things that might screw ksh up. My motivation for switching was so that my uucp shell (~!) would give me korn shell.
