A shell, also called "the command line", provides the traditional user interface for the Unix operating system and for Unix-like systems. Users direct the operation of the computer by entering command input as text for a shell to execute. |

!!Change A Users Login Shell |
|
|
10 |
|
|
|
11 |
Note : A normal user can only change their own login shell, whereas the super user can change the login shell for any user account. |
|

The syntax is : |
|
|

|

BenStaz |
15 |
*chsh -s /path/to/shell/ ~[user_account~] |
1 |
BenStaz |

So If I am a superuser and I want the login shell for user account 'staz' to be sh then I would type: |
1 |
BenStaz |
18 |
|
|
|
19 |
*shsh -s /bin/sh staz |
|
|

|
|
|

Keep in mind a normal user can only change their login shell to one that is listed in ''/etc/shells''. |
|
|

|
|
|

!!/etc/shells |
|
