I think we should stick to one shell. Bash. The installer could definitely
put that at the top of gsh, and Can you add a jira and we can work
on it? Or if you want to you can edit the grouperInstaller in git and submit
a pull request :)

Main thing is that people know about the need to edit gsh/ -- It's
blurry to me at the moment (clearly the earlier coffees have worn off),
but I dimly seem to recall the installer asking for the location of a
shell of some sort (/bin/sh?), so perhaps getting the installer to set
this up is not so farfetched. In any case, the installer already asks
for the location of dos2unix to strip the carriage returns out of the script...

Making symlinks on Unix systems to shells is probably "Not a Good
Idea(tm)" and regardless the shells themselves should normally be in a
user's PATH somewhere, and something like

pete@orca:~$ BASH=`which bash`; echo $BASH

... should function on Unixen of different pedigrees. I'm happy to try
experimenting with bash vs sh (sh on Ubuntu points to dash, we run
Grouper on RH/Centos or SuSE at work) to see if the existing gsh works
with those shells.

I can look into this and try a couple of things and get back to you if
you like.

Thanks and Best, -- pete
