What the restricted shell provides
For Linux and UNIX computers, Centrify provides a customized Bourne shell, dzsh, to serve as the restricted shell environment. The dzsh restricted shell supports environment variables, job control, command history, and the specific command rights you define. For example, you can use the up-arrow key in the dzsh shell to recall previously-entered commands. You can also set a limit to the command history available by adding HISTSIZE=n to the $HOME/.dzshrc file.
For most operations, working in the dzsh shell is similar to working in an unrestricted shell except that the command set available is limited to the command rights you add to the environment.
