  • How to change default login shell permanently in linux

    In Red hat Linux the default shell you login to is /bin/bash but in case you want to change the default login shell follow the below procedure

    To check the currently logged in shell
    # echo $SHELL

    To view all the available shells in your machine
    # chsh -l

    You can also view the available shell details from the below file
    # less /etc/shells

    To change the shell temporarily

    To do this just provide the full path of the shell you want to use. But this is just a temporary change as next time you switch terminal you will login to the default shell

    [root@test2 ~]# /bin/sh
    As you see above my shell prompt changed from /bin/bash to /bin/sh

    To change the shell prompt permanently

    # chsh -s /bin/sh
    Changing shell for root.
    Shell changed.

    [root@test2 ~]#
    But as you notice even though our shell was changed successfully but still we see bash shell prompt.

    NOTE: To make the changes affect you need to log out and log back in
    Using username "root".
    root@'s password:
    Last login: Fri Mar 21 10:15:03 2014 from
    -sh-4.1# echo $SHELL

    So now as I try to login I see my default login shell is changed to /bin/sh

    Which file is responsible for assigning shell by default?

    What if you want next time you create a user, he/she should get different shell and every time you don't change their shell manually

    Check the below file
    # cat /etc/default/useradd
    # useradd defaults file

    As you see the SHELL argument has /bin/bash as default. Just change this value to any shell you want to provide for a new user.
