before I try to change to my preferred shell, one general question to the experts:
is there any specific functional/technical reason for the decision to have zsh as default shell in Manjaro x86 but only bash in Manjaro ARM??
Specific reason why zsh is default in Manjaro x86 but not in Manjaro ARM?
This may help you with the procedure as it is not really intuitive:
I cannot answer the question, though.
We just like our regular old bash. You can still install zsh, fish or any shell you want. We just use bash as it’s reliable and people know it.
