Ren (command)
Computer command From Wikipedia, the free encyclopedia
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.

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