You can use the "chsh" command.

Code:

$ man chsh

Here's another how-to:

If you're just wanting to run the shell temporarily (instead of making it your default), I'm pretty sure it's as simple as making sure you have the desired shell installed, then running it from the command line of your existing shell (works for me under NetBSD, anyway; never had the desire to switch shells in Linux). The 'exit' command should take you back to the default.

Thanks.

After I switch to ksh can I start writing the shell scripting and execute this, does this work?

Thanks,

Actually, that's a pretty good how-to. I have that bookmarked. I should have linked it in my first post here. I forgot. Thanks, infidel!

Thanks for the info, its very useful. Also is there any way to find which shell Iam using.

vtel57 · 06-13-2007, 10:48 PM

Code:

$ echo $SHELL

Example from my terminal:

Quote:

vtel57@ericsbane03:~$ echo $SHELL
/bin/bash

Hi vtel57,

I did the following and changed the shell, but when I tried to find which shell I am using it gives back /bin/bash, please see below.

$ chsh
Changing shell for db2admin.
Password:
New shell [/bin/bash]: /bin/ksh
Shell changed.
$ echo $SHELL
/bin/bash
$

Thanks,
TJ

Its should give /bin/ksh instead of /bin/bash. Is this correct?

User logout... log back in.

Try

Code:

yum -y install ksh

vtel57 · 06-14-2007, 12:50 PM

Er... yeah. I was assuming you had ksh already installed. If not, use custangro's suggestion.

Luck!

It must be installed otherwise it wouldn't be listed in /etc/shells and you wouldn't be able to chsh.

As vtel57 said, you need to log out and back in.
