PATH (variable) PATH is an environment variable on Unix-like operating systems, DOS, OS/2, and Microsoft Windows, specifying a set of directories where executable programs are located. In general, each executing process or user session has its own PATH setting.
Root directory. 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 ...
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. The latest version is 3.0, released on 3 June 2015.
Path (computing) A path (or filepath, file path, pathname, or similar) is a string of characters used to uniquely identify a location in a directory structure. It is composed by following the directory tree hierarchy in which components, separated by a delimiting character, represent each directory. The delimiting character is most commonly the ...
route (command) In computing, route is a command used to view and manipulate the IP routing table in Unix-like and Microsoft Windows [1] operating systems and also in IBM OS/2 and ReactOS. [2] Manual manipulation of the routing table is characteristic of static routing.
File URI scheme. In programming, a file uniform resource identifier (URI) scheme is a specific format of URI, used to specifically identify a file on a host computer. While URIs can be used to identify anything, there is specific syntax associated with identifying files. [1][2]
Multics had a pwd command (which was a short name of the print_wdir command) [11] from which the Unix pwd command originated. [12] The command is a shell builtin in most Unix shells such as Bourne shell, ash, bash, ksh, and zsh. It can be implemented easily with the POSIX C functions getcwd() or getwd().
A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD systems use /home/ username or /usr/home/ username and Windows systems since Windows Vista use \Users\ username .
