It provides a number of convenient features for interactive use that are not available with the Bourne shell, including filename completion, command aliasing, history substitution, job control, and a number of built-in commands. As with the Bourne shell, the C shell provides variable, command and filename substitution.

csh first appeared in 2BSD, and was originally created by Bill Joy. While Bourne shells are more popular, csh-style shells are still fairly popular especially in the BSD community & academia.

is an an enhanced version of csh, almost all versions of csh encountered nowadays are actually tcsh.

Programming in csh is a controversial topic. For one viewpoint, see this article.
