GNU Find Utilities (also known as findutils) is a GNU package which contains implementations of the tools find and xargs. BusyBox is a utility that provides several stripped-down Unix tools in a single executable file, intended for embedded operating systems with very limited resources.

(Files are by default listed in columns and sorted vertically.) dircolors: Set up color for ls: install: Copies files and set attributes ln: Creates a link to a ...

Server data (data for services provided by system). /sys: In some Linux distributions, contains a sysfs virtual filesystem, containing information related to hardware and the operating system. On BSD systems, commonly a symlink to the kernel sources in /usr/src/sys. /tmp: A place for temporary files not expected to survive a reboot.
In DOS systems, file directory entries include a Hidden file attribute which is manipulated using the attrib command. Using the command line command dir /ah displays the files with the Hidden attribute. In addition, there is a System file attribute that can be set on a file, which also causes the file to be hidden in directory listings.
In some cases, zero-byte files may be used to convey information like file metadata (for example, its filename may contain an instruction to a user viewing a directory listing such as documents-have-been-moved-to-partition-D, etc.); or to put in a directory to ensure that it is non-empty, since some tools such as backup and revision control ...
In computer science, a sparse file is a type of computer file that attempts to use file system space more efficiently when the file itself is partially empty. This is achieved by writing brief information ( metadata ) representing the empty blocks to the data storage media instead of the actual "empty" space which makes up the block, thus ...
It was created by Chris Mason in 2007 [15] for use in Linux, and since November 2013, the file system's on-disk format has been declared stable in the Linux kernel. [ 16 ] Btrfs is intended to address the lack of pooling, snapshots , integrity checking , data scrubbing , and integral multi-device spanning in Linux file systems . [ 9 ]
