Type Command

In computing, ren (or rename) is a command in various command-line interpreters (shells) such as COMMAND.COM , cmd.exe , 4DOS, 4NT and Windows PowerShell. It is used to rename computer files and in some implementations (such as AmigaDOS [1] ) also directories. It is analogous to the Unix mv command. However, unlike mv, ren cannot be used to move files, as a new directory for the destination file may not be used. Alternatively, move may be used if available. On versions of MS-DOS that do not support the move command (older than 6.00), the user would simply copy the file to a new destination, and then delete the original file. A notable exception to this rule is DOSBox, in which ren may be used to move a file, since move is not supported.

Description of the RENAME command of RT-11SJ displayed on a VT100.

The command is available in the operating systems Digital Research CP/M, [2] MP/M, [3] [4] Cromemco CDOS, [5] MetaComCo TRIPOS, [6] DOS, IBM OS/2, [7] Microsoft Windows, [8] ReactOS, [9] SymbOS, and DexOS.

Multics includes a rename command to rename a directory entry. It can be contracted to rn. [10]

Stratus OpenVOS, [11] DEC RT-11, [12] OS/8, [13] RSX-11, [14] Intel ISIS-II, [15] iRMX 86, [16] TOPS-20, [17] Zilog Z80-RIO, [18] TSC FLEX, [19] Microware OS-9, [20] DR FlexOS, [21] IBM/Toshiba 4690 OS, [22] HP MPE/iX, [23] THEOS/OASIS, [24] and OpenVMS [25] also provide the rename command which in some cases can be contracted to ren.

The rename command is supported by Tim Paterson's SCP 86-DOS. [26] On MS-DOS, the command is available in versions 1 and later. [27] DR DOS 6.0 also includes an implementation of the ren and rename commands. [28]

In Windows PowerShell, ren is a predefined command alias for the Rename-Item Cmdlet which basically serves the same purpose. [29]

TSL PC-MOS includes an implementation of rename. [30] Like the rest of the operating system, it is licensed under the GPL v3. [31]

It is also available in the open source MS-DOS emulator DOSBox.

Example

>ren filename newname >ren *.htm *.html

Another example. This will rename a default video found in Windows 7 with a new name:

>rename"C:\Users\Public\Videos\Sample Videos\Wildlife.wmv""Wildlife2.wmv"

The first parameter may contain a drive and a path, but the second parameter must contain only the new filename.

To remove certain characters of a file name in Microsoft Windows command prompt (XP & Higher) :

>rename"abcd*.txt""////*.txt"

This will remove abcd from the file name.

Notes:

  1. Same number of / as the number of initial characters to remove.
  2. Double quotes for both arguments.
  3. It doesn't remove . from file name

dir (command) Directory information command on various operating systems

In computing, dir (directory) is a command in various computer operating systems used for computer file and directory listing. 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). On some systems, a more graphical representation of the directory structure can be displayed using the tree command.

mkdir Directory creation command on various operating systems

The mkdir command in the Unix, DOS, DR FlexOS, IBM OS/2, Microsoft Windows, and ReactOS operating systems is used to make a new directory. It is also available in the EFI shell and in the PHP scripting language. In DOS, OS/2, Windows and ReactOS, the command is often abbreviated to md.

In computing, rmdir is a command which will remove an empty directory on various operating systems.

In computing, CLS is a command used by the command-line interpreters COMMAND.COM and cmd.exe on DOS, Digital Research FlexOS, IBM OS/2, Microsoft Windows and ReactOS operating systems to clear the screen or console window of commands and any output generated by them. It does not clear the user's history of commands, however. The command is also available in the DEC RT-11 operating system, in the open-source MS-DOS emulator DOSBox and in the EFI shell. In other environments, such as Linux and Unix, the same functionality is provided by the clear command.

In computing, echo is a command that outputs the strings that are passed to it as arguments. It is a command available in various operating system shells and typically used in shell scripts and batch files to output status text to the screen or a computer file, or as a source part of a pipeline.

<span class="mw-page-title-main">CHKDSK</span> System tool in DOS, OS/2 and Windows

In computing, CHKDSK is a system tool and command in DOS, Digital Research FlexOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows and related operating systems. It verifies the file system integrity of a volume and attempts to fix logical file system errors. It is similar to the fsck command in Unix and similar to Microsoft ScanDisk, which co-existed with CHKDSK in Windows 9x and MS-DOS 6.x.

more (command) Terminal pager available on various operating systems

In computing, more is a command to view the contents of a text file one screen at a time. It is available on Unix and Unix-like systems, DOS, Digital Research FlexOS, IBM/Toshiba 4690 OS, IBM OS/2, Microsoft Windows and ReactOS. Programs of this sort are called pagers. more is a very basic pager, originally allowing only forward navigation through a file, though newer implementations do allow for limited backward movement.
