C shell

In Unix, a popular command interpreter; pronounced "sea shell."

Developed at the University of California at Berkeley as part of the BSD development as an alternative to the Bourne shell. In addition to the features found in the Bourne shell, the C shell adds integer arithmetic, a history mechanism that can recall past commands in whole or in part, aliasing of frequently used commands, job control, and a built-in set of operators based on the C programming language used for writing shell scripts.
