GNU units converts quantities expressed in various systems of measurement to their equivalents in other systems of measurement. Like many similar programs, it can handle multiplicative scale changes. It can also handle nonlinear conversions such as Fahrenheit to Celsius, and it can perform conversions from and to sums of units, such as converting between feet plus inches and meters. Beyond simple unit conversions, units can be used as a general-purpose scientific calculator which keeps track of units in its calculations. You can form arbitrary complex mathematical expressions of dimensions including sums, products, quotients, powers, and even roots of dimensions. In this way, you can ensure accuracy and dimensional consistency when working with long expressions which involve many different units which may combine in complex ways. The units are defined in an extensive, well-annotated data file which defines over 2,500 units. You can also provide your own file to supplement or replace the standard file.
Unnamed un-names unwanted DNS entries. It was written to solve the problem of upstream DNS servers inserting bogus records for NXDOMAINs. It can be used to filter unwanted domain names like ads, porn, time wasters, etc. It is modular, so extensions are easy. Extensions can be written in Lua or compiled as shared objects.
Untarka extracts TAR (Unix Tape ARchive) files without calling any external programs. It supports and autodetects multiple compression methods (.tar, .tar.Z, .tar.gz, .tar.bz2, .Z, .gz, and .bz2). Unix devices, sockets, hard links, symlinks, owners, and permissions are ignored during extraction.
