Hello Andrew, Yes, you seem to understand my problem best.  That
system('bash') bandage works great.  If you'd been right about my
renaming octave to bash or the other way around, that would have been
a real zinger.  I wasn't able to verify that though.  Maybe I DID do a
messy symlink somewhere.    my personal .profile, .bashrc and the
system level /etc/profile and /etc/bashrc offer no hints.  Whatever is
going on, Octave's 'system' command doesn't recognize the alias 'la'
that I define for 'ls -la' in my .profile, either if doesn't get as
far as my .profile or it is calling a different shell.  When I delete
Octave.app and start Terminal I get the following:
"

Welcome to Darwin!
xxx:~ xxx$ exec '/Applications/Octave.app/Contents/Resources/bin/octave'
-bash: /Applications/Octave.app/Contents/Resources/bin/octave: No such
file or directory
-bash: exec: /Applications/Octave.app/Contents/Resources/bin/octave:
cannot execute: No such file or directory
xxx:~ xxx$
"


Tricky, huh?
I'll dig around for other config files that bash or Terminal dig
through before initializing.  I guess at this point the problem is no
longer in this list's domain.  Thanks much for your help up to now.
