The pcregrep command is an implementation of grep that uses Perl regular expression syntax. [17] Similar functionality can be invoked in the GNU version of grep with the -P flag. [18] Ports of grep (within Cygwin and GnuWin32, for example) also run under Microsoft Windows. Some versions of Windows feature the similar qgrep or findstr command. [19]
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.
The operating systems the archivers can run on without emulation or compatibility layer. Ubuntu's own GUI Archive manager, for example, can open and create many archive formats (including Rar archives) even to the extent of splitting into parts and encryption and ability to be read by the native program.
The file manager has a toolbar with options to create an archive, extract an archive, test an archive to detect errors, copy, move, and delete files, and open a file properties menu exclusive to 7-Zip. The file manager, by default, displays hidden files because it does not follow Windows Explorer's policies.
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).
Zstandard combines a dictionary-matching stage with a large search window and a fast entropy-coding stage.It uses both Huffman coding (used for entries in the Literals section) [15] and finite-state entropy (FSE) – a fast tabled version of ANS, tANS, used for entries in the Sequences section.
Decompression speed is higher than bzip2, but lower than gzip. Compression can be much slower than gzip, and is slower than bzip2 for high levels of compression, and is most useful when a compressed file will be used many times. [4] [5] XZ Utils consists of two major components: xz, the command-line compressor and decompressor (analogous to gzip)
mod_gzip is an external extension module for the Apache HTTP Server v1 and v2. It allows using the Gzip compression method for a significant reduction of the volume of web page content served over the HTTP protocol. mod_gzip can be compiled into Apache as either a static or dynamic module.
