This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
A move command that moves a directory entry to a new directory was first implemented within Multics. It can be contracted to mv. [1] Later, the mv command appeared in Version 1 Unix [2] and became part of the X/Open Portability Guide issue 2 of 1987. [3] The version of mv bundled in GNU coreutils was written by Mike Parker, David MacKenzie, and ...
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.
On MS-DOS, the command is available in versions 6 and later. [7] In Windows PowerShell, move is a predefined command alias for the Move-Item Cmdlet which basically serves the same purpose. The FreeDOS version was developed by Joe Cosentino. [8] DR DOS 6.0 includes an implementation of the move command. [9] The open-source MS-DOS emulator DOSBox ...
The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. If pushd is not provided with a path argument , in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories.
The ln shell command normally uses the link [7] system call, which creates a hard link. When the ln -s flag is specified, the symlink() system call is used instead, creating a symbolic link. Symlinks were introduced in 1982 in 4.1a BSD Unix from U.C. Berkeley. [8] The following command creates a symbolic link at the command-line interface (shell):

File descriptors for a single process, file table and inode table. Note that multiple file descriptors can refer to the same file table entry (e.g., as a result of the dup system call [3]: 104 ) and that multiple file table entries can in turn refer to the same inode (if it has been opened multiple times; the table is still simplified because it represents inodes by file names, even though an ...
