hsh is a command-line driven user interface to your system with a full-screen curses interface instead of the scrolling terminal style output of traditional shells. The main purpose of hsh compared to a traditional shell is to make job output easier to work with. Each job's output is viewed and manipulated independently. This means, among other things, that you can incrementally create pipelines, and that a rampant process can't trash all the output of your session. Its syntax is designed for human use, not a programming language. It has a dynamic configurable interface, making useful information accessible.
Tiny Bash Server (TBS) is a small HTTP server. It allows CGI style scripting with .htsh files, which may contain Bash code embedded within normal HTML. TBS uses netcat to bind itself to open port(s). Multiple instances of the server may be run (on different ports and with different docroots) using separate configuration files. TBS comes with all the basic features you expect of a Web server: serving HTML/CSS, handling POST/GET forms, etc. It also passes selected environment variables for use with CGI scripting in .htsh files. However, it is highly not recommended to run TBS on any sort of production system. This is because, as a server, TBS is relatively slow, potentially insecure, and has fewer features than full-fledged servers like Apache HTTPD. A potential use for TBS is to develop browser-based frontends to bash scripts for local usage.
gcp (Goffi's CoPier) is a command line file copying tool, loosely inspired by cp, but with high level functionality like a progress indicator, the ability to continue copying multiple files even when there is a problem with one of them, and the use of a journal to track successful copying. File names can be fixed to ensure compatibility with the target filesystem. If you launch a copy operation when another is already running, the files are added to the first queue to avoid hard drive thrashing. You can keep track of files you have copied, and re-copy them later. gcp is approximately option-compatible with cp.
Salut à Toi (or SàT: "Hi to You") is an XMPP/Jabber client with multi-frontends. You can use it on a desktop (Wix), with a console interface (Primitivus), as a command-line tool (jp), or on the Web (Libervia). A plugin architecture is used to make it modular. With SàT, you can perform all the expected XMPP functions (instant messaging, multi-user chat, file transfert, etc.), but you can also use your email client (MUA) to read and send your XMPP messages, play games, do microblogging, pipe Unix command results, make scripts, etc.
ShellCheck is a static analysis tool for shell scripts. Its goals are to point out and clarify typical beginner's syntax issues that causes a shell to give cryptic error messages, to point out and clarify typical intermediate level semantic problems that causes a shell to behave strangely and counter-intuitively, and to point out subtle caveats, corner cases, and pitfalls that may cause an advanced user's otherwise working script to fail under future circumstances.
