I have a question egarding the BASH shell:

whenever the system default shell is KSH OR CSH in that many case to
complete the commands by using TAB key I type bash and change the
shell (I am not sure though this really change the shell as changing
the system SHELL is diffrent procedure)
My questiion is - does typing bash and executing the commands via bash
shell impacts the system ? Hope you got what I am trying to say ?

Thanks in Advance.

You might want to set the shell prompt editing mode as emacs, like

# set -o emacs

The only impact on the system (and it's a very, very tiny overhead) is to run an additional process.

Hi

The shells make no real difference, except when you start scripting with it, and then it depends on which one you like.
If you prefer bash, then change your login shell to bash.

All built in scripts, and hopefully all your custom scripts start with the line "#!/bin/sh" or similar to run in it the correct shell.
So, you can change your login shell to bash, so that you do not have to switch between the two.

run the command:

vipw
(This will start the vi editor and open the user file.)

Then change the last bit for you user to point to the correct location of bash.

This can be /usr/bin/bash, /bin/bash, /usr/local/bin/bash depending on the OS. Make sure you use the correct path, or it will disable your login.

example from Ubuntu:
root:x:0:0:root:/root:/bin/bash

I hope that helps.
