It is used to move one or more files or directories from one place to another. [2] The original file is deleted, and the new file may have the same or a different name. The command is analogous to the Unix mv command and to the OpenVOS move_file and move_dircommands. [3]
In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was originally developed to write data to sequential I/O devices with no file system of their own, such as devices that use magnetic tape.
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. Consider the following subsection of a Unix filesystem, which shows a user's home directory (represented as ~ ) with a file, text.txt , and three subdirectories.
The copy command is supported by Tim Paterson's SCP 86-DOS. [23] Under IBM PC DOS/MS-DOS it is available since version 1. [24] A more advanced copy command is called xcopy. The equivalent Unix command is cp, the CP/M command is PIP. The command is analogous to the Stratus OpenVOS copy_file command. [25]

Both commands are available in FreeCOM, the command-line interface of FreeDOS. [8] In Windows PowerShell, pushd is a predefined command alias for the Push-Location cmdlet and popd is a predefined command alias for the Pop-Location cmdlet. Both serve basically the same purpose as the pushd and popd commands.
Using mv requires the user to have write permission for the directories the file will move between. This is because mv changes the content of both directories (i.e., the source and the target) involved in the move. When using the mv command on files located on the same filesystem, the file's timestamp is not updated.
Pygame was originally written by Pete Shinners to replace PySDL after its development stalled. [2] [8] It has been a community project since 2000 [9] and is released under the free software GNU Lesser General Public License [5] (which "provides for Pygame to be distributed with open source and commercial software" [10]).
