The parallel project allows for simple parallel and distributed processing from shell scripts. In particular, the programs accept lines of shell code on the standard input and run these lines in parallel. The parallelism can be either on the local machine or on a cluster, if a small amount of time is taken to set up SSH. Additionally, the distributed version includes a degree of fault tolerance.
Teractualizar is a daemon to synchronize files using SFTP as a secure transfer method. It also features the ability to upload and execute any application or command, which can be used to manage clusters of computers. It requires only baaic Unix commands, an SSH client, and the SFTP service. Currently, the client side of this system only runs on Windows NT (and derivative operating systems).
Dim is a utility to help you track the changes of items (sets composed of multiple files). It provides commands to handle the complete lifecycle of version control operations: create a library, register users (code authors), create items, save local versions, branch, clone, export, import, remove, merge, archive, replicate library content over the network or the filesystem, and access the full history and browse differences at the library, item, file, line, or word level. Dim is a single self-documented POSIX shell script. It just uses standard Unix utilities like awk, diff, tar, and openssl.
homeTVstream is a collection of shell scripts and a PHP-based Web page for watching TV on your LAN computers. It is based on VLC, and encodes and streams video using port 8080 in an MMS stream. You can watch it with VLC by using the URL mmsh://yourserverip:8080/, with any other MMS-capable player by using the URL mms://yourserverip:8080/, or just by opening the TV page in your Web browser.
flipflip's podcast downloader is a script that downloads podcasts. Is has options to limit the number of podcasts to download, to rename the downloaded files based on rules, and to tag the MP3 files with custom content or with content derived from the feed metadata. The program is very small and has very few dependencies (id3v2 and wget).
The MirBSD Korn Shell (mksh) is an actively developed successor of pdksh (the Public Domain Korn Shell), aimed at producing a shell good for interactive use, but with the primary focus on scripting. It is intended to be portable to most *nix-like operating systems as long as they're not too obscure. mksh incorporates improvements from OpenBSD and Debian, as well as bugfixes and enhancements developed for the MirOS, FreeWRT, and MidnightBSD projects and Android. The emacs command line editing mode is UTF-8 capable, and Byte Order Marks are ignored in scripts. The shell supports large files, as well as all pdksh and some csh, AT&T ksh, zsh, and GNU bash features, is compatible with the Bourne shell and POSIX (within limits), has no limit on array sizes, and incorporates some other useful builtins and features. While being already fast and small (without losing functionality), flags to make it even smaller can be given at compile time. An interactive shell reads "~/.mkshrc" on startup.
