octave stole my Terminal

This is an OS X problem. Everytime I start my terminal, it starts octave. And when I enter 'quit', it quits the shell. So then, the only way I can run commands is by typing, for example, "system('ls')". There is nothing in my .bashrc or .profile that is sneaky.
Here is what happens when I start a new shell in Terminal and then check my processes: " Last login: Wed Sep 12 13:49:59 on ttyp1 Welcome to Darwin! exec '/Applications/Octave.app/Contents/Resources/bin/octave' XXX:~ XXX$ exec '/Applications/Octave.app/Contents/Resources/bin/octave' GNU Octave, version 2.9.13 Copyright (C) 2007 John W.

Right Moc, but I wouldn't say this is a problem, this is new and wanted and
depends on how Octave.app is started. If you double-click the icon or call from command line open /Applications/Octave.app then we start a new process (Terminal.app) and therefore we need to terminate that process again after the call of 'quit' or 'exit' (Apple App behavior). So what to do with the 'terminated process Terminal.app' - the Terminal never gets active anymore!? Set in your Preferences of Terminal.app that the window should be closed if bash is exited, so that you can see the feature completely working. The other solution is to start up octave from the command line by just typing eg. /Applications/Octave.app/Contents/Resources/bin/octave (or you already have created a link to this file placed eg. in /usr/bin and then simply call octave - read Readme.html of *.dmg about how to do it) then you get back to the bash after the call of "quit" (Unix shell command behavior) because Octave runs on top of bash in the same Terminal.app. Without promise I hope that it also works like this on your PPC platform?!

If I understand Moc's problem correctly, I don't think it's "exec"'s behavior that he's having problem with. The problem is every time he launches Terminal, octave is being run, instead of his usual shell (be it /bin/sh or /bin/bash). My first rather wacky guess would be ... Moc, are you sure your shell isn't "/usr/bin/octave" or something like that? :) Here's a rather contrived example on Debian: I created a "test" user with "shell" of /usr/bin/octave, and when I try to open a shell as that user ... === plato:~# grep test /etc/passwd test:x:1001:1001:Tester:/home/test:/usr/bin/octave plato:~# su - test su: Authentication service cannot retrieve authentication info.

I don't know for sure what additional rc scripts are run in OS X, but you might want to check system files like /etc/profile and /etc/bashrc, etc, etc. You should check any files that your own .bashrc or .bash_profile or .profile, or .login is sourcing. And, if you are really interested in finding which process is launching that octave, you might try "ps afu" instead. I have to admit I don't know all the switches to ps, but at least in GNU's version of ps (in BSD compatible mode, I think), "f" seems to bring up a tree view that shows the child-parent relationship between processes. If this doesn't work, you can ... well, look at "man ps" on your system to see what option will let you see PPID (parent process ID). And until you find a real solution, this bandage that I found might work for you too :) === -su:13> system("exec bash") test@plato:~$ === Regards, Andrew |

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: " Last login: Thu Sep 13 15:51:40 on ttyp1 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. -seth _______________________________________________ Help-octave mailing list Help-octave@... https://www.cae.wisc.edu/mailman/listinfo/help-octave |
