Greetings:
I upgraded to MacOS 10.3 (Panther) last night and IDL got trashed. In
the processed of reinstalling it, including all the Unix config
files/scripts, I discovered that the shell had be changed to bash from
the tsch that it had been. Since my Unix skills are limited and since
the info pages at rsinc.com are written for the tsch shell I am at an
impass.
I need to know how to reset the default shell and get the scripts
reset. I think I do the latter by editing the .cshrc and .tcshrc
file in the Users/MyDir/ to include:
source RSI-DIR/idl_6.0/bin/idl_setup
and/or find out where .bashrc file is and how to set its script for
the equivalent of the above command.
Thanks
Patrick Ford

Did anybody answer this guy's question?
Go to /Applications/Utilities/Netinfo Manager and work through the
panes from / => users => youraccount and change the default shell to
whatever you want. Save the changes and you're done. You'll need
the admin password, of course.

This isn't a script, its just a list of commands. In bash and other
Bourne-like-shells you can "source" (i.e. run) this list of commands
using ".", i.e.
$ . idl_setup.bash
Shell scripts start with "#!/bin/bash", or something like this; think of
it like the distinction in IDL between files you can "@" and files you
can ".run".
A better method might be to make your own set of aliases and environment
variables in a .bashrc or the equivalent startup file. I also like to
make IDL_DIR just be "idl" which is a symbolic link to idl_6.0, etc.
This facilitates running multiple versions of IDL in the "probation"
period when new releases come out.
Good luck,
JD
