Chsh

Change the shell that the user uses when logging in, using bash by default. If shell,chsh is not given on the command line, you will be prompted to enter a shell. Chsh will accept the full pathname of any executable file on the system. However, if the shell is not listed in the "/ etc/shell" file, a warning is issued. On the other hand, it can be configured to accept only the shell listed in this file, unless you are a root user.

The scope of this command: RedHat, RHEL, Ubuntu, CentOS, SUSE, openSUSE, Fedora.
