lsh is a free implementation (in the GNU sense) of the ssh version 2 protocol, currently being standardised by the IETF SECSH working group.
metashell is a lightweight, heavy punch, interactive, intelligent command line shell. The difference lies in its ability to determine a file's data type, and automatically run your desired applications. It uses file data types (MIME types) to determine a file's type, and then using user-defined applications automatically opens the file.
new_script consists of two programs designed to help you write shell scripts.
NOSH logs to a system file and(or) send mail when logins are attempted to disabled accounts.

sash is a stand-alone shell with many built-in commands.
scponly is an alternative 'shell' (of sorts) for system administrators who would like to provide access to remote users to both read and write local files without providing any remote execution priviledges.
