bash-3.00$: to rasputin~$: ?

[Sidoh]

No, it has bash.  Notice how I was able to launch it?  I just had ~/.bashrc containing a "link" to /etc/profile on a slackware box, so some things there weren't expected, but here's the output for you anyway:

Code: [Select]

[mullins@grays ~]$ bash
bash-3.00$ exit
exit
[mullins@grays ~]$ which bash; whereis bash
/bin/bash
bash: /bin/bash /usr/local/bin/bash.OBSOLETE /usr/local/bin/bash /usr/share/man/man1/bash.1.gz

I don't think I have access to change it.  Maybe I can just launch bash when I first log in?

Edit: seems to work fine doing that.  I just have to type "exit" twice. >_>

I know FSU requires us to email the Help Desk to have our shell changed.  Maybe you have to request a shell change from some authority too?

[Sidoh]

I would imagine so, but this seems to be a valid workaround for now?

Yeah, that works, have tcsh execute bash on startup

[iago]

I don't know if it works on tcsh, but try running "exec bash" -- exec, if it works, replaces the current running process (ie, tcsh) with the new one (bash), so you only have to exit once.

[nslay]

Sidoh, I noticed on the motd that they have you use /usr/local/bin/npasswd to change the password.  Perhaps there is a /usr/local/bin/nchsh?

[rabbit]

Now my only problem is that it doesn't show # when I su to root

Don't think so

mullins@grays:~$ ls /usr/local/bin/nchsh
ls: /usr/local/bin/nchsh: No such file or directory

Excellent!  Thanks much, iago!

[Sidoh]

Haha.  When I got to class today, I logged into the same Linux box I was SSH'ing (grays, as you might have guessed) and FC4 bombed right after logging in.  At first, I thought my account was disabled for some strange reason and I was all freaked out.  About two seconds after that, though, I realized I was messing around with this last night.  I just replaced ~/.cshrc with the backup of the old one I made and appended it with exec /bin/bash and it works great.    I feel sorry for all of the suckers typing pwd.  What's the advantage csh has over bash?

[Newby]

What's the advantage csh has over bash?

As far as syntax, there isn't much. There are a few different built-in commands (man builtin I think...) but the syntax is the big difference.

[iago]

I don't know, but a lot of people love csh.  I seem to remember Tmp saying he likes it.   

[Newby]

By the way, if you wanted to use bash because it shows a directory in the prompt... you can do that to the prompt in csh too.

I know the syntax is different.  I was wondering if there were significant differences in performance, robustness, etc.

Every computer in the Linux labs here uses it.  There must be something...

I want this to work with ssh too.  I don't think that will work with it?  I found their login script (it's ~/.cshrc), and the variable defining the prompt syntax (set prompt=""). Do I need to fix that?

I'd love to switch to bash, since that's what I'm familiar with.  I've tried to use for, do, etc a few times and it throws errors!  Is there a way to change it for one user?

Excuse me for suggesting inefficiency here, but since ~/.cshrc is in your ~ directory, you could edit that for yourself. If I understand correctly, shells have no problem running shells on top of themselves. For example, in bash, you can type csh to run csh. The same principle can be reversed to run bash over csh, no?
