I am trying to set ZSH as my default shell, however it keeps reverting back to bash.

I have tried this code:

sudo chsh -s $(which zsh)

I've also tried:

sudo chsh -s /bin/zsh 

Also tried these commands without sudo. Any ideas on what else I need to do. When running ZSH from within bash it loads up and works fine but I'd like to set it as the default shell.

If you use sudo it will change the shell not for your working user but for root. Just using

chsh -s /bin/zsh

without sudo should work (but you need to login again to see the change).

I have the same problem and the answer doesn't solve it – Aswin Murugesh Jul 21 '13 at 16:11

you can also run sudo chsh -s /bin/zsh userName – Dr Gorb Sep 30 at 10:49
Note: I had to restart my system before this would take effect. – KevinO Oct 12 at 0:38

I found this on superuser forum

Open /etc/passwd:

sudo vi /etc/passwd

Find the line with your username:

username:x:1634231:100:Your Name:/home/username:/bin/bash

and replace bash with zsh:

username:x:1634231:100:Your Name:/home/username:/bin/zsh

Log out and log in back for the changes to take effect.

If zsh is not /bin/zsh then chsh won't work. On Ubuntu it is /usr/bin/zsh. so doing chsh -s /usr/bin/zsh or chsh -s `which zsh` should work. Also need to re-login to desktop session.

Strange, the "accepted" answer didn't work for me as I got

chsh: PAM: Authentication failure

To solve this issue edit your /etc/passwd and make sure it points to the zsh location. (You can find this by running "which zsh") In my case my user called "webmaster" looked like this: enter image description here
