Login shells

These shells are available:

Bourne shell (/bin/sh): First shell to be developed; includes wildcards, basic command language. Also available in a restricted version.
Bourne shell with job control (/bin/jsh): Includes full job control found in the Korn and C shells.
C shell (/bin/csh): Different language syntax from Bourne and Korn shell family (similar to the C programming language). Includes command history recall (reuse of recently issued commands without retyping them), aliases (defining alternative names for commands), and limited ability to redirect input and output.
Korn shell (/bin/ksh): Compatible superset of Bourne shell facilities; includes command history editing (editing and reissuing previously typed commands interactively) and aliases. In addition, supports job control (manipulation of background processes), and extended language syntax. Recommended shell. (Also known as the POSIX shell, /u95/bin/sh, part of the IEEE POSIX 1003.2 standard.) Also available in a restricted version.
Windowing Korn shell (/bin/wksh): Windowing version of the Korn shell that supports the creation of graphical applications using shell commands.
uucp: Non-interactive shell for UUCP login accounts that use uucico(1Mbnu). Do not assign this to a normal user account. See ``Adding uucp logins''.
