I installed ZSH and didn't like it and I want to revert back to bash. I uninstalled ZSH before I tried changing the default shell. I uninstalled ZSH and then ran the commands chsh and sudo chsh --shell=/bin/bash $USERNAME but it seems that no matter what commands I use to change the shell it still says that I'm using the ZSH shell when I run echo $?. I'm pretty new to Linux/Ubuntu so can someone point me in the right direction?

  • You do understand that the "shell", kept in /etc/passwd only applies at login time?

    Have you logged out and back in after changing your login shell?

you can take a look at the list of shells you have installed with:
cat /etc/shells

For example, to change current shell to bash, you can use the chsh command :
chsh -s /bin/bash

or use the usermod command to change the shell of a user:
sudo usermod -s /bin/bash putHereTheUserName

You can confirm the sheel of the user on /etc/passwd (it's the last element of each line):
cat /etc/passwd | grep putHereTheUserName


Remove the old symlink first

sudo rm -v /bin/sh

Now, create a new symlink, assuming that bash is in /bin directory

sudo ln -sv /bin/bash /bin/sh

This should do the trick for you.

    /bin/sh on Ubuntu is supposed to point to /bin/dash, and nobody uses /bin/sh as their login shell. This bad advice, and unrelated to the problem at hand.

  • @muru FYI on my Ubuntu /bin/sh is linked to /bin/bash by default and it uses bash as the default login shell. May 23, 2016 at 9:11

    Then you must have made it so. Ubuntu has used /bin/dash as /bin/sh for years. FYI: wiki.ubuntu.com/DashAsBinSh And I said: nobody uses /bin/sh as their login shell.
