Fsck
The system utility fsck (''file system consistency check'') is a tool for checking the consistency of a file system in Unix and Unix-like operating systems, such as Linux, macOS, and FreeBSD. A similar command, CHKDSK, exists in Microsoft Windows and its predecessor, MS-DOS. Pronunciation There is no agreed pronunciation. It can be pronounced "F-S-C-K", "F-S-check", "fizz-check", "F-sack", "fisk", "fishcake", "fizik", "F-sick", "F-sock", "F-sek", "feshk", the sibilant "fsk", "fix", "farsk" or "fusk". Use Generally, fsck is run either automatically at boot time, or manually by the system administrator. The command works directly on data structures stored on disk, which are internal and specific to the particular file system in use - so an fsck command tailored to the file system is generally required. The exact behaviors of various fsck implementations vary, but they typically follow a common order of internal operations and provide a common command-line interface to the user. ...

Btrfs
Btrfs (pronounced as "better F S", "butter F S", "b-tree F S", or simply by spelling it out) is a computer storage format that combines a file system based on the copy-on-write (COW) principle with a logical volume manager (not to be confused with Linux's LVM), developed together. It was initially designed at Oracle Corporation in 2007 for use in Linux, and since November 2013, the file system's on-disk format has been declared stable in the Linux kernel. According to Oracle, Btrfs "is not a true acronym". Btrfs is intended to address the lack of pooling, snapshots, checksums, and integral multi-device spanning in Linux file systems. Chris Mason, the principal Btrfs author, stated that its goal was "to let inuxscale for the storage that will be available. Scaling is not just about addressing the storage but also means being able to administer and to manage it with a clean interface that lets people see what's being used and makes it more reliable".

Lost And Found
A lost and found (American English) or lost property (British English), or lost articles (also Canadian English) is an office in a public building or area where people can go to retrieve lost articles that may have been found by others. Frequently found at museums, amusement parks and schools, a lost and found will typically be a clearly marked box or room in a location near the main entrance. Some lost and found offices will try to contact the owners of any lost items if there are any personal identifiers available. Practically all will either sell, give away, or discard items after a certain period has passed to clear their storage. History In Japan, the lost-and-found property system dates to a code written in the year 718. The first modern lost and found office was organized in Paris in 1805. Napoleon ordered his prefect of police to establish it as a central place "to collect all objects found in the streets of Paris", according to Jean-Michel Ingrandt, who was appointed t ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Fuck
''Fuck'' is an English-language expletive. It often refers to the act of sexual intercourse, but is also commonly used as an intensifier or to convey disdain. While its origin is obscure, it is usually considered to be first attested to around 1475 CE. In modern usage, the term ''fuck'' and its derivatives (such as ''fucker'' and ''fucking'') are used as a noun, a verb, an adjective, an interjection or an adverb. There are many common phrases that employ the word as well as compounds that incorporate it, such as ''motherfucker'', '' fuckwit'', '' fuckup'', ''fucknut, fucktard,'' and ''fuck off''. ''Fuck'' is considered profanity and therefore unsuitable for use in normal public discourse. Offensiveness It is unclear whether the word has always been considered vulgar or, if not, when it first came to be used to describe (often in an extremely angry, hostile or belligerent manner) unpleasant circumstances or people in an intentionally offensive way, such as in the term ''mo ...

E2fsprogs
e2fsprogs (sometimes called the e2fs programs) is a set of utilities for maintaining the ext2, ext3 and ext4 file systems. Since those file systems are often the default for Linux distributions, it is commonly considered to be essential software. List of utilities Included with e2fsprogs, ordered by ASCIIbetical order, are: ;badblocks : search a device for bad blocks ;blkid : locate/print block device attributes ;chattr : change file attributes on a Linux file system ;debugfs : used to manually view or modify internal structures of the file system ;dumpe2fs : which prints superblock and block group information. ;e2freefrag : report free space fragmentation information ;e2fsck : an fsck program that checks for and corrects inconsistencies ;e2image : save critical ext2/ext3/ext4 filesystem metadata to a file ;e2label : change the label on an ext2/ext3/ext4 filesystem ;e2undo : replay an undo log for an ext2/ext3/ext4 filesystem ;e4defrag : online defragmenter for ext4 filesystem ;fi ...

List Of File Systems
The following lists identify, characterize, and link to more thorough information on Computer file systems. Many older operating systems support only their one "native" file system, which does not bear any name apart from the name of the operating system itself. Disk file systems Disk file systems are usually block-oriented. Files in a block-oriented file system are sequences of blocks, often featuring fully random-access read, write, and modify operations. * ADFS – Acorn's Advanced Disc filing system, successor to DFS. * AdvFS – Advanced File System, designed by Digital Equipment Corporation for their Digital UNIX (now Tru64 UNIX) operating system. * APFS – Apple File System is a next-generation file system for Apple products. * AthFS – AtheOS File System, a 64-bit journaled filesystem now used by Syllable.

JFS (file System)
Journaled File System (JFS) is a 64-bit journaling file system created by IBM. There are versions for AIX, OS/2, eComStation, ArcaOS and Linux operating systems. The latter is available as free software under the terms of the GNU General Public License (GPL). HP-UX has another, different filesystem named JFS that is actually an OEM version of Veritas Software's VxFS. In the AIX operating system, two generations of JFS' exist, which are called ''JFS'' (''JFS1'') and ''JFS2'' respectively. In other operating systems, such as OS/2 and Linux, only the second generation exists and is called simply ''JFS''. This should not be confused with JFS in AIX that actually refers to JFS1. History IBM introduced JFS with the initial release of AIX version 3.1 in February 1990. This file system, now called ''JFS1 on AIX'', was the premier file system for AIX over the following decade and was installed in thousands or millions of customers' AIX systems. Historically, the JFS1 file system is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiWikiWeb
The WikiWikiWeb is the first wiki, or user-editable website. It was launched on 25 March 1995 by programmer Ward Cunningham to accompany the Portland Pattern Repository website discussing software design patterns. The name ''WikiWikiWeb'' originally also applied to the wiki software that operated the website, written in the Perl programming language and later renamed to "WikiBase". The site is frequently referred to by its users as simply "Wiki", and a convention established among users of the early network of wiki sites that followed was that using the word with a capitalized ''W'' referred exclusively to the original site. History The software and website were developed in 1994 by Cunningham in order to make the exchange of ideas between programmers easier. The concept was based on the ideas developed in HyperCard stacks that Cunningham built in the late 1980s. On March 25, 1995, he installed the software on his company's (Cunningham & Cunningham) website, c2.com. Cunningham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Usenet
Usenet () is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980.''From Usenet to CoWebs: interacting with social information spaces'', Christopher Lueg, Danyel Fisher, Springer (2003), , Users read and post messages (called ''articles'' or ''posts'', and collectively termed ''news'') to one or more topic categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are threaded, as with web forums and BBSs, though posts are stored on the server sequentially.The jargon file v4.4.7 , Jargon File Archive.
