You can use the User Settings tools to change the login shell for the Administrative User account. The following shells are preinstalled and supported on your server:
C shell (csh), a popular command interpreter that has its origins in Berkeley UNIX, is particularly suited for interactive use. It offers many features, including an ability to recall and modify previous commands, a facility for creating command shortcuts, shorthand notation for pathnames to home directories, and job control.
tcsh, an enhanced version of csh, is almost entirely upward compatible with csh, so whatever you know about the C shell you can apply immediately to tcsh. But tcsh goes beyond csh, adding capabilities like a general purpose command line editor, spelling correction, and programmable command, file, and user name completion.
Bourne shell (sh). The Bourne shell is the oldest of the currently popular shells and is the most widely available.
Bourne Again shell (bash). An extension of the Bourne shell, bash includes such enhancements as command line editing, key bindings, integrated programming features, command completion, and control structures.
Korn shell (ksh). Provides all the features of csh and tcsh together with a shell programming language similar to that of the original Bourne shell.
To change your shell, follow the steps below:
Click the Change your shell link from the User Settings menu.
Select one of the shells from the dropdown list.
Click Set Shell.
The next time you log into your server via SSH or Telnet, you will default to the new shell.
