Tar (computing)

In computing, tar is a computer software utility for collecting many files into one archive file for distribution or backup purposes.

Description

The name is derived from tape archive, as it was originally developed to write data to sequential I/O devices.

The archive data sets created by tar contain various file system parameters, such as:

• Time stamps
• Ownership
• file access permissions
• Directory organization

Standards

The file structure to store this information was later standardized in POSIX.1-1988 and later POSIX.1-2001. and became a format supported by most modern file archiving systems.
