 | | The Bourne shell was the shell used in early versions of Unix and became a de facto standard; every Unix-like system has the equivalent of the Bourne shell. |
 | | On systems using a windowing system, some users may never use the shell directly, though on Unix systems, the shell is still the implementation language of system startup scripts, including the program that starts the windowing system, the program that dials into the Internet, and many other essential functions. |
 | | Today, the C shell is not in wide use; it has been superseded by other shells such as the Tenex C shell (tcsh), the Korn shell (ksh), and the GNU Bourne-Again shell (bash). |
