The title of this article is incorrect because of technical limitations. The correct title is tcsh.

tcsh is a Unix shell, based on (and compatible with) the C shell (csh). It is essentially the C shell with (programmable) filename completion, command-line editing, and a few other features.

The 't' in tcsh comes from the T in TENEX, an operating system which inspired the author of tcsh Ken Greer with their command-completion feature. Ken Greer worked on tcsh in the late 1970s at the Carnegie-Mellon University. Paul Placeway from the Ohio State University continued work on it in the 1980s, and since then it was maintained by numerous people. Wilfredo Sanchez, formerly lead engineer on Mac OS X, worked on tcsh in the early 1990s at the MIT.

tcsh replaced the C shell as default shell on most modern BSD descendant operating systems.
