install bash if not installed already and change the SHELL parameter in /etc/profile, if you want to use it by your all user. otherwise you just change your own SHELL parameter in .profile.

WARNING: You must NOT change root's shell to anything but /sbin/sh. You can invoke any other shell later, if you aren't in single user mode.

>ahsan: change the SHELL parameter in /etc/profile

This is next to useless. If you want to change the shell, you edit /etc/passwd or use chsh(1).

You may also have to add bash to /etc/shells.

Hi ,

>> I want to install bash and use it instead of sh

For which "user id" you need to change...?

for "root" account "NO" "NO" you should not change

how to change the shell for "user id"

Check the below file "to check you have bash shell exits in you server"

# strings /etc/shells

than proceed as below

you need root access to change
Example:-

vi /etc/passwd
user1:*:133:20:For Database Access,,,:/home/user1:/usr/bin/sh --> erase and change to /usr/bin/bash

or

you Use SAM ->User & Groups->User->select the User -->modify

Thanks,
Johnson

root uses a "statically linked" version of sh found in /sbin/sh. Others typically use /bin/sh (or whatever) which either may not be on a mounted filesystem or rely on libraries that aren't available when the system is first started in maintenance mode.

as noted above, once you've downloaded and installed bash, you can start it from the command line once you are logged in.

In single-user mode, many file systems may
not be mounted, including the ones with the
run-time libraries which "bash" normally
needs. /bin/sh does not need these
libraries, so it works even when "/" is the
only mounted file system.

You might be able to do something like
exec bash
at the end of root's ".profile" file. If it
works, you'll be running "bash". If it
fails, you should still be ok (still running
/bin/sh).

The command is chsh(1), root not needed.

>Check /etc/shells "to check if bash shell exists in your server"

You only need to update shells(4) if you want to use ftp.
