Wsh is a remote Unix and Windows NT shell that works via HTTP. The client script provides a shell-like prompt, encapsulating user commands into HTTP POST requests and sending them to the server script. The server script extracts and executes commands and returns STDOUT and STDERR output. Features include command line history support, file upload/download, and it can work through an HTTP proxy server.
Sethi Search Utility is a simple command line utility to submit a search to Google, Yahoo!, or MSN and show the (text) results on standard output. Support for several search engines is included. It's currently in serious need of a re-write, especially to avoid scraping and become a good engine using the search APIs provided.
DIRT is a simple directory stack utility that lets the user use the same directory stack across terminals and sessions. The stack of directories is stored in a file (.dirtpile) in your home directory. All shell sessions access the same file, and thus, all of them use the same stack. DIRT supports jumping to specific entries, push, pop, swap the CWD with the top of the stack, and jump to the top of the stack. A set of CSH shell aliases are also included, and required for proper functioning.
The d command runs a command in the background and redirects its output to a file. The output file is annotated with start and end time, the actual command used, cwd, host, etc. You can ask the d command to extract the last command from the output file and run it again, you can ask it to append to the file or not, and other goodies. It comes with handy little programs to look at the output, tail it, etc. It is sort of trivial, but has been streamlined over many years.
sash-plus-patches is a collection of patches for the well known standalone shell, sash. The key features are the chroot, pivot_root, and losetup functions. These functions provide interfaces to the respective Linux system calls. They are especially useful when sash is used in a initial ramdisk ("initrd") environment. In addition, simple shell variable expansion support has been added.
Clam Shell is a simple shell, designed to be a testbed for user interface ideas. It is a modular shell where the modules can be loaded or unloaded at runtime to expand or contract the functionality of the shell. This lets each user have a set of tools that they like to use, rather than one monolithic shell.
Telephone Control Daemon allows a user to dial a system and perform some predefined commands. It uses a voice modem (tested with Rockwell) to provide a DTMF-based interface to the user. It is useful for systems that only have a temporary Internet connection but may need to be connected at the demand of some remote user.
