tar archive files usually have the file suffix .tar (e.g. somefile.tar). A tar archive file contains uncompressed byte streams of the files which it contains. To achieve archive compression, a variety of compression programs are available, such as gzip, bzip2, xz, lzip, lzma, zstd, or compress, which compress the entire tar archive. Typically ...
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.
gzip is a file format and a software application used for file compression and decompression.The program was created by Jean-loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by GNU (from which the "g" of gzip is derived).

A tar.gz is created by joining the files in tar and then compressing with gzip. In computing, solid compression is a method for data compression of multiple files, wherein all the uncompressed files are concatenated and treated as a single data block. Such an archive is called a solid archive.
There are also programs that create self-extracting archives on Unix as shell scripts, which utilize programs like tar and gzip (which must be present in the destination system). [ citation needed ] Others (like 7-Zip or RAR ) can create self-extracting archives as regular executables in ELF format.
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 ...
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.
