MacShell is a Unix-like command line interface for the Macintosh. It performs a limited impersonation of the Unix C shell, and contains abbreviated versions of a set of Unix-style file management, file finding, and content searching utilities. It also has a no-frills <32k text editor built-in.
MacShell is free, courtesy of Fred Videon. It may not be sold in any form.
This version performs approximations of the Unix utilities in the list that follows.
