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.

    quick answer that worked for me: logging out and then logging back in to the desktop session fixed it for me.

Just using chsh:

chsh -s $(which zsh)

without sudo should work. If you use sudo it will change the shell not for your working user but for root

Finally, log out of your computer and log back in.

    Note: I had to restart my system before this would take effect.

    Rebooting on Linut Mint 19.2 is needed to have zsh take over. sudo reboot gets the job done.

    Please log out and login if not working. Feb 16, 2020 at 15:29

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.

    You should be very careful with this approach - it's not usually the best idea to go mucking around with /etc/passwd

    Even though I didn't use this method, it helped me verify the effect of chsh -s `which zsh`

    To Log out and log in back is very important step. Maybe it is should even be somehow emphasized.

You may also do this:

open your bashrc file in your favourite editor

sudo nano ~/.bashrc

then add the line below top of the file

exec zsh

It will execute the command every time you load the terminal and run your zsh shell.

    and it will also break all your non-interactive jobs (scp for example).

    Sorry for the downvote, but changing /etc/passwd or chsh are better solutions and more reliable.

  • Thanks that did it. @Timo I did the change on /etc/passwd and or chsh but my default kept going back to bash. I added exec zsh as per posted response and it worked.

    Adding exec zsh is most likely going to break your Gnome Shell session.

  • This was the only one that worked for me on the work machine with active directory, my username is always not found, whoami works fine, but certain commands such as chsh always cannot locate my username

I had an issue with permissions to change shell under the current user but next helps me (you should set correct 'zsh' folder for your computer):

sudo chsh -s /bin/zsh <myUserName>
  • very helpful, thank you!

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.

    On my Ubuntu VPS it's /bin/zsh Dec 9, 2015 at 12:39
  • On my Ubuntu, I see it in both /bin/zsh and /usr/bin/zsh

    On mine (14.04, with zsh from main repo), there are two zsh's, and they are both two-layer symlinks: /usr/bin/zsh -> /etc/alternatives/zsh-usrbin -> /bin/zsh5 and /bin/zsh -> /etc/alternatives/zsh -> /bin/zsh5

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:

  • I believe it's supposed to ask for a password. I got the same error on my previous mint install. Current one worked fine though Dec 9, 2015 at 12:40
  • Someone else had the same problem, and it turned out they had ran chsh -s zsh, which made their passwd entry incorrect.

As well as chsh (or editing /etc/passwd, which does the same thing), you might need to edit the settings in your terminal emulator (Gnome terminal, Konsole, xfce4-terminal, etc). Your profile will probably have a login shell, which will be run when you open a new tab instead of the shell in /etc/passwd.
In Konqueror it's Settings | Edit Current Profile | Command.
