The control structures, expression grammar, history mechanism and other features in Holub's SH were identical to those of the C shell. In 1988, Hamilton Laboratories began shipping Hamilton C shell for OS/2. [23] It included both a csh clone and a set of Unix-like utilities. In 1992, Hamilton C shell was released for Windows NT.

On many systems, csh may be a symbolic link or hard link to TENEX C shell (tcsh), an improved version of Joy's original version ...
