Changing default shell in ubuntu

I faced this problem when I created a new account using command line where the default shell of my new account is /bin/sh. After googling around, I found 2 useful solutions which are listed below:

1. Change user entry in /etc/passwd
a) edit /etc/passwd using any editor

• $ vi /etc/passwd
  

b) find the line that belongs to the user (foo) that we about to modify

• foo:x:1001:1001::/home/foo:/bin/sh

c) change from /bin/sh to /bin/bash

• foo:x:1001:1001::/home/foo:/bin/bash

d) save
e) Logout and login back

2. Use chsh command
a) type chsh

• $ chsh

b) You will be asked for password. Enter your password
c) This screen will appear

• Enter the new value, or press ENTER for the default
  Login Shell [/bin/sh]:

d) Put /bin/bash at the menu and press Enter

Done :)
