Description:
Shell with C-like syntax
The C shell was originally written at UCB to overcome limitations in the Bourne shell. Its flexibility and comfort (at that time) quickly made it the shell of choice until more advanced shells like ksh, bash, zsh or tcsh appeared. Most of the latter incorporate features original to csh. . This package is based on current OpenBSD sources.
