The mkdir (make directory) command in the Unix, DOS, DR FlexOS, [1] IBM OS/2, [2] Microsoft Windows, and ReactOS [3] operating systems is used to make a new directory. It is also available in the EFI shell [4] and in the PHP scripting language. In DOS, OS/2, Windows and ReactOS, the command is often abbreviated to md.
Changes the permissions of a file or directory cp: Copies a file or directory dd: Copies and converts a file df: Shows disk free space on file systems dir: Is exactly like "ls -C -b". (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 ...
A directory is a logical section of a file system used to hold files. Directories may also contain other directories. The cd command can be used to change into a subdirectory, move back into the parent directory, move all the way back to the root directory or move to any given directory.
In computing, dir (directory) is a command in various computer operating systems used for computer file and directory listing. [1] It is one of the basic commands to help navigate the file system . The command is usually implemented as an internal command in the command-line interpreter ( shell ).
Make's dependency ordering and out-of-date checking makes the build process more robust and more efficient. The makefile allowed for better organization of build logic and often fewer build files. Make is widely used in part due to its early inclusion in Unix, starting with PWB/UNIX 1.0, which featured a variety of software development tools. [3]
In a hierarchical file system (that is, one in which files and directories are organized in a manner that resembles a tree), a directory contained inside another directory is called a subdirectory. The terms parent and child are often used to describe the relationship between a subdirectory and the directory in which it is cataloged, the latter ...
The directory stack underlies the functions of these two commands. It is an array of paths stored as an environment variable in the CLI, which can be viewed using the command dirs in Unix or Get-Location -stack in PowerShell. The current working directory is always at the top of the stack.
It is sometimes called the current working directory (CWD), e.g. the BSD getcwd [1] function, or just current directory. [2] When a process refers to a file using a path that does not begin with a / (forward slash), it is interpreted as a relative to the process's working directory.
