dtrx intelligently extracts many different archive types. It will get the contents from tar, zip, rpm, deb, and cpio archives, as well as compressed files, with one simple command. It helps keep your filesystem sane by putting every archive's contents into a dedicated directory, and making sure the owner can read and write whatever's extracted. It can even recursively extract archives.
surl is a URL shortening command line application that supports various sites. It supports stdin or filename input. It grabs the URLs, converts them, and returns the same text that was used in the input. It is known to work with a wealth of services, such as bit.ly, tinyurl.com, and others.
vcprompt prints a short string, to be included in your shell prompt, with barebones information about the current working directory for various version control systems. It is designed to be small and lightweight rather than comprehensive. It has varying degrees of recognition for Mercurial, Git, Subversion, CVS, and Fossil working copies.
PYBAG implements a portable bag and is intended for fast synchronization and backup. It lets you use a portable digital storage device to carry your electronic documents similar to the way you can use a bag to carry paper documents. You can synchronize the bag with your original files easily. If a synchronization conflict occurs, it will be reported. You can specify rules for automatic conflict resolution. With PYBAG, you can backup files and synchronize any changes made to the original files with the bag. The synchronization process will only copy changed files. The program is cross-platform and independent from the OS and filesystem. You may easily synchronize files between Windows and Linux, for example. Symbolic links are supported on all systems (if the OS or filesystem does not support symlinks, then they are emulated). This program has a GUI and a command line interface.
