(The tar program in its own does not compress; it just stores multiple files within one tape archive.) Files can be returned to their original state using uncompress. The usual action of uncompress is not merely to create an uncompressed copy of the file, but also to restore the timestamp and other attributes of the compressed file. For files ...
RPM files consist of metadata concatenated with (usually) a cpio archive. Newer RPM systems also support other archives, as cpio is becoming obsolete. cpio is also used with initramfs. .shar application/x-shar Shell archive: Unix-like A self-extracting archive that uses the Bourne shell (sh). .LBR .LBR: CP/M DOS A system for storing multiple files.
ZIP is an archive file format that supports lossless data compression.A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common.
BTLZ is an LZ78-based algorithm that was developed for use in real-time communications systems (originally modems) and standardized by CCITT/ITU as V.42bis. When the trie-structured dictionary is full, a simple re-use/recovery algorithm is used to ensure that the dictionary can keep adapting to changing data. A counter cycles through the ...
The 7-Zip implementation uses several variants of hash chains, binary trees and Patricia trees as the basis for its dictionary search algorithm. In addition to LZMA, the SDK and 7-Zip also implements multiple preprocessing filters intended to improve compression, ranging from simple delta encoding (for images) and BCJ for executable code. It ...
Aegis Authenticator, showing time-based one-time passwords. Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF ...
A single file format, such as 7z, can support multiple different compression algorithms, including LZMA, LZMA2, PPMd, and BZip2. [citation needed] Decompression utilities must be able to handle both the file format and the algorithm used when expanding self-extracting or standard archives. Depending on the options used to create a self ...
