How do I go back to bash?
Simple user method
Many users or others who have seen this have had a feeling of disgust over this choice which to them seems "amateur" and illogical. While this bothers me, I don't think bash will become the default terminal for users (non-root, root stayed in bash by default to allow the chroot command to work), and you can fall back on bash.
Kaisen Linux's default terminal is ZSH installed with the oh-my-zsh framework.
You are only one user and you only have one account installed, use the following command (as your user and not as root):
chsh -s /bin/bash
The next time you reconnect to your session, you will be back in bash.
Multiple user method
Type this when adding a user with the useradd command to give them the bash shell by default:
sudo useradd -s /bin/bash user
Modify useradd configuration
In the file /etc/default/useradd, change the following line:
After that, with the useradd command the bash shell will be set by default, and you will no longer need to specify -s option.
When updating the shadow package, select the option "N" or "O" to keep your configurations.
Type this when adding a user with the adduser command to give them the bash shell by default:
sudo adduser --shell /bin/bash user
Modify adduser configuration
In the file /etc/adduser.conf, change the following line:
After that, with the adduser command the bash shell will be set by default, and you will no longer need to specify --shell option.
When updating the adduser package, select the option "N" or "O" to keep your configurations.
