CURSEL is a freeware FMLI (Forms and Menu Language Interpreter) implementation for Linux and UNIX. CURSEL interprets Menu description files, which are simple text files, describing a character GUI (Menus, forms, text files) for character terminals (xterm, vt100, etc.). Pipes, shell escapes, backquoted expressions, and file redirection are supported, and when compiled with ncurses 5, CURSEL supports color.
GNU Bash is an sh-compatible command language interpreter that executes commands read from the standard input or from a file. Bash also incorporates useful features from the Korn and C shells (ksh and csh). Bash is intended to be a conforming implementation of the IEEE POSIX Shell and Tools specification (IEEE Working Group 1003.2).
GNU shtool is a compilation of small but very stable and portable shell scripts into a single shell tool. All ingredients were in successful use over many years in various free software projects. The compiled shtool program is intended to be used inside the source tree of free software packages. There it can overtake various (usually non-portable) tasks related to the building and installation of an free software package.
new_script is a program that creates shell script templates. It was developed to facilitate rapid creation of well-formed shell scripts containing the features expected in a production quality script, including traps for signal handling, command line option and argument processing, help messages invoked with the "-h" or "--help" options, and a framework for internal documentation.
PHP Shell is a shell wrapped in a PHP script. It's a tool you can use to execute arbiritary shell-commands or browse the filesystem on your remote Web server. This replaces, to a degree, a normal telnet-connection. You can use it for administration and maintenance of your Web site using commands like ps, free, du, df, and more.
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.
imp3sh (interactive MP3 shell) is a flexible playlist manipulation shell and song player/streamer. It natively supports MP3 and Ogg Vorbis files/URLs with the Xaudio Asynchronous library for Linux, but can use external players to play any format. It has over 90 builtin commands, and many commonly-used shell features (such as job control, command history, tab completion, aliasing, and more).
CLEX is a file manager with a full-screen user interface written in C with the curses library. It displays directory contents (including file status details) and provides features like command history, filename insertion, or name completion in order to help the user to construct commands to be executed by the shell (there are no built-in commands). CLEX is easily configurable and all its features are explained in the on-line help.
