New page
It is a simple process to change any user's default shell to any available shell which is install on the Linux system.<br>

<p>

Become the root super user:

<pre style="color:blue">$ su - root</pre>

<u>OR</u> if you are set up with sudo:

<br>

<pre style="color:blue">$ sudo su - root</pre>

<br>

Your command prompt should now have a # in it instead of a $, indicating you are now the root super user, as shown here:<br>

(Note: root@localhost may be displayed as root@your_machinename in the following examples and your display prompt might be slightly different - just ensure it contains the #)

<br>

<pre style="color:blue">[root@localhost ~]#</pre>

<br>

Edit the passwd file in the /etc directory:

<pre style="color:blue">[root@localhost ~]#vi /etc/passwd</pre>

Search for the username you are wanting to change shells for using the slash("/") vi search function:

With the passwd file open in the vi text editor, tap the "/" key which brings up the "/" in the bottom left corner of the vi editor, waiting for you to type your search word. Type the name of the user login name and hit the ENTER key to find the entry. Then, using the right cursor movement arrow key, move your cursor all the way to the end of the line, to the very first letter of the name of the shell the user is currently set up to use. For example, say I want to change jamie's default shell from sh to bash, as root, I'd open /etc/passwd in vi and search for jamie:

<br>

<pre style="color:blue">[root@localhost ~]#vi /etc/hosts</pre>

<br>

<pre  style="color:blue">root:x:0:0:root:/root:/bin/bash

bin:x:1:1:bin:/bin:/sbin/nologin

daemon:x:2:2:daemon:/sbin:/sbin/nologin

.

.

.

jamie:x:1000:1000:Jamie Rubinstein:/home/jamie:/bin/sh

</pre>

<br>

Use the right cursor arrow key to move to the letter "s" for the current shell, /bin/sh, and tape the c key and then w key one  after the other fairly quickly,which will put you in "Insert"  mode, stating so in the bottom left corner of your screen, and deleting the "sh" part of "/bin/sh" and allowing you to type in text:

<br>

<pre  style="color:blue">jamie:x:1000:1000:Jamie Rubinstein:/home/jamie:/bin/

.

.

.

-- INSERT --

</pre>

<br>

Type in "bash",  without the quotes, and then hit the "Esc" key  once.  The "-- INSERT --" at the bottom left corner of your screen will  be gone, indicating you are no longer  in "INSERT" mode, but instead in the other VI mode, command mode. The updated line should now look like this:

<pre style="color:blue">jamie:x:1000:1000:Jamie Rubinstein:/home/jamie:/bin/bash</pre>

<br>

To save the file and exit the vi editor, while in  command mode(no longer have "-- INSERT --" at bottom left corner of vi screen), tap the colon(":") key once, which will apear at the bottom left corner of your screen,and then tap the x key(lower case), which will apear aftre the colon,like this:

<pre style="color:blue">:jamie:x:1000:1000:Jamie Rubinstein:/home/jamie:/bin/bash

.

.

.

~

~

:x</pre>

<br>

Hit the "ENTER" key at this point to save and exit. The effect takes effect the next time the user logs into the system.
