Bourne shell ($) - The Bourne shell was the original shell
program for the UNIX environment. It is the default shell for the
Solaris computing environment. Stephen Bourne developed the Bourne
shell for the AT&T System V.2 UNIX environment. This shell does
not have aliasing, history or command line editing capabilities and
is used primarily by system administrators. The Bourne shell prompt
is a dollar sign ($), which is similar to a DOS C:> prompt.
Korn shell ($) - The Korn shell is a superset of the Bourne
shell and was developed by Stephen Korn at Bell Labs. It has many of
the Bourne shell features plus added features such as aliasing,
history, and command line editing. This is the most widely used
shell and is the industry standard for system users. The Korn shell
prompt is also a dollar sign ($).
Note - Examples given in this
course are based primarily on the Korn shell.
C shell (%) - A shell based on the C programming language.
Like the Korn shell, it has additional features such as aliasing and
history. The C shell was developed by Bill Joy of Sun Microsystems
and is still widely used today. The C shell prompt is a percent sign
(%).
