In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.
pax is an archiving utility available for various operating systems and defined since 1995. [1] Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility pax that could support various archive formats with useful options from both archivers.
tar cJf keep.txz keep # archive then compress the directory ./keep/ into the file ./keep.txz tar xJf keep.txz # decompress then extract the file ./keep.txz creating the directory ./keep/ xz has supported multi-threaded compression (with the -T flag) [ 6 ] since 2014, version 5.2.0; [ 7 ] since version 5.4.0 threaded decompression has been ...
The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program.
A text-mode browser/extractor: plugin for dar files in mc (Midnight Commander). A scheduler / command-line frontend known as SaraB allows the Towers of Hanoi, Grandfather-Father-Son, or any custom backup rotation strategy, and modifications are available for PAR file support. Extended versions known as bzSaraB and baras are also available.
There were two purposes to the liquid seal: first, to draw off some of the tar and liquor, as the gas from the retort was laden with tar, and the hydraulic main could rid the gas of it, to a certain degree; further tar removal would take place in the condenser, washer/scrubber, and the tar extractor. Still, there would be less tar to deal with ...
One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1]
For example, archiving a collection of files with tar and then compressing the resulting archive file with gzip results a file with .tar.gz extension. This approach has two goals: It follows the Unix philosophy that each program should accomplish a single task to perfection, as opposed to attempting to accomplish everything with one tool. As ...
