Changing to a different shell
The Terminal application lets you use a command-line interface to control the underlying BSD UNIX operating system. In each Terminal window, a "shell" program takes your keyboard input and executes the commands.
Mac OS X includes these shells: /bin/bash (the default shell), /bin/csh (tcsh), /bin/zsh, and /bin/ksh. You can install and use different shells if you wish. A system administrator can change your shell default or you can specify a different shell to use in Terminal Preferences.
- Choose Terminal > Preferences.
- Select "Execute this command" and type the path of the shell you want to use.
For more information about the features of the shells, enter "man" and the name of the shell.
