Pax differs from cpio by recursively considering the content of a directory; to disable this behavior, POSIX pax has an option -d to disable it. The pax command is a mish-mash of cpio and tar features. Like tar, pax processes directory entries recursively, a feature that can be disabled with -d for cpio-style behavior.
In a computer file system, and primarily used in the Unix and Unix-like operating systems, the root directory is the first or top-most directory in a hierarchy. [1] It can be likened to the trunk of a tree, as the starting point where all branches originate from. The root file system is the file system contained on the same disk partition on ...
Directory structure. In computing, a directory structure is the way an operating system arranges files that are accessible to the user. Files are typically displayed in a hierarchical tree structure .
Defragmentation, shrinking, and rebalancing operations require extents to be relocated. However, doing a simple copy-on-write of the relocating extent will break sharing between snapshots and consume disk space. To preserve sharing, an update-and-swap algorithm is used, with a special relocation tree serving as scratch space for affected ...
Filesystem Hierarchy Standard. The Filesystem Hierarchy Standard ( FHS) is a reference describing the conventions used for the layout of Unix-like systems. It has been made popular by its use in Linux distributions, but it is used by other Unix-like systems as well. [1] It is maintained by the Linux Foundation.
In computing, tree is a recursive directory listing command or program that produces a depth-indented listing of files. Originating in PC- and MS- DOS, it is found in Digital Research FlexOS, [1] IBM / Toshiba 4690 OS, [2] PTS-DOS, [3] FreeDOS, [4] IBM OS/2, [5] Microsoft Windows, [6] and ReactOS. A version for Unix and Unix-like systems is ...
Bcachefs is a copy-on-write (COW) file system for Linux -based operating systems. [3] Features include caching, [4] full file-system encryption using the ChaCha20 and Poly1305 algorithms, [5] native compression [4] via LZ4, gzip [6] and Zstandard, [7] snapshots, [4] CRC-32C and 64-bit checksumming. [3] It can span block devices, including in ...
cp (Unix) In computing, cp is a command in various Unix and Unix-like operating systems for copying files and directories. The command has three principal modes of operation, expressed by the types of arguments presented to the program for copying a file to another file, one or more files to a directory, or for copying entire directories to ...
