Replacing Bash with Fish in dom0

Would like to install Fish and fzf in dom0.

Are there going to be any issues if do a chsh with the dom0 user?

Pur a password to root user and try to change your user shell. If it fails after a reboot, log in as root to revert the shell change and remove root password

I saw your blog post about fish. Are you also using it in dom0 or only appvms

I did not try on dom0 but I use it so rarely that I just type fish when I need it

My dom0 didn’t have chsh installed, but manually editing /etc/passwd, I was able to change the user’s shell to /usr/bin/fish. I didn’t encounter any problems.

You can use usermod program to change the shell of a given user.
