which is the primary purpose of using the tar command
tar (computing) 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 (t)ape (ar)chive, as it was originally developed to write data to sequential I/O devices with no file system of their own. The archive data sets created by tar contain various file system parameters, such as name, time stamps, ownership, file access permissions, and directory organization. The command line utility was first introduced in the seventh edition of unix (v7) in January 1979, replacing the tp program.[1] The file structure to store this information was later standardized in POSIX.1-1988[2] and later POSIX.1-2001[3] and became a format supported by most modern file archiving systems.
Fuel dumping Fuel dumping operations are coordinated with air traffic control, and precautions are taken to keep other aircraft clear of such areas. Fuel dumping is usually accomplished at a high enough altitude where the fuel will dissipate before reaching the ground. Fuel leaves the aircraft through a specific point on each wing, usually closer to the wingtips and further away from engines, and initially appears as more liquid than vapor.
