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.
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.)
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 with gzip, compress, bzip2, lzip, xz, or zstd Multiple Multiple Yes The "tarball" format combines tar archives with a file-based compression scheme (usually gzip). Commonly used for source and binary distribution on Unix-like platforms, widely available elsewhere. Xarchiver supports the .tar.zst Archive/Compression format on Unix-like ...
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]
For example, if the underlying file is a tar archive, this can allow extracting any undamaged files, even if other parts of the archive are damaged. As for the file format, special emphasis has been put on enabling integrity checks by means of an integrated 32-bit checksum for each compressed stream; [ 3 ] this is used in combination with the ...
ZPAQ is an open source command line archiver for Windows and Linux.It uses a journaling or append-only format which can be rolled back to an earlier state to retrieve older versions of files and directories.
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.
