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.
libarchive provides command-line utilities called bsdtar and bsdcpio. [3] These are complete re-implementation based on libarchive. [9] [10] These are the default system tar and cpio on FreeBSD, NetBSD, macOS and Windows. [5] There is also bsdcat, designed to decompress a file to the standard output like zcat. [11]
A single file container/archive that can be reconstructed even after total loss of file system structures. .tar application/x-tar Tape archive: Unix-like A common archive format used on Unix-like systems. Generally used in conjunction with compressors such as gzip, bzip2, compress or xz to create .tar.gz, .tar.bz2, .tar.Z or tar.xz files.
archivemount is a FUSE-based file system for Unix variants, including Linux. Its purpose is to mount archives (e.g. tar, tar.gz, etc.) to a mount point where it can be read from or written to as with any other file system. This makes accessing the contents of the archive, which may be compressed, transparent to other programs, without ...
The file extension changes to indicate the compression method. [9] [2] data archive - A tar archive named data.tar contains the actual installable files. Compressing the archive with gzip, bzip2, lzma or xz and zstd is supported. The file extension changes to indicate the compression method. [9] [2]
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.

Files compressed by compress are typically given the extension ".Z" (modeled after the earlier pack program which used the extension ".z"). Most tar programs will pipe their data through compress when given the command line option "-Z". (The tar program in its own does not compress; it just stores multiple files within one tape archive.)
