2. List of acceptable shells.

$ cat /etc/shells
/bin/sh
/bin/csh
/bin/tcsh
/usr/local/bin/bash
/usr/local/bin/rbash

2.Changing the Shell

$ bash
[user@server ~]$

The easiest way to permanently change the default shell is to use chsh or chpass. Running this command will open the editor that is configured in the EDITOR environment variable, which by default is set to vi(1). Change the Shell: line to the full path of the new shell.

Alternately, use chsh -s which will set the specified shell without opening an editor. For example, to change the shell to bash:

$ whereis bash
bash: /usr/local/bin/bash
$ chsh -s /usr/local/bin/bash
[user@server ~]$ echo $0
-bash
