Change Default Shell For A User

You can change the default shell program for a particular unix user with the chsh command. Just tell it what shell program you want to use (e.g. bash or zsh) and which user the change is for:

$ [sudo] chsh -s /usr/bin/zsh username

This command needs to be invoked with root privileges.

This command updates the entry for that user in the /etc/passwd file.
