Ren (command)

From Wikipedia, the free encyclopedia

In computing, ren (or rename) is a command in various DOS, OS/2 and Microsoft Windows command line interpreters (shells) such as COMMAND.COM, cmd.exe, 4DOS/4NT and Windows PowerShell. It is used to rename files and in some implementations also directories. It is analogous to the Unix mv command. RT-11, RSX-11 and OpenVMS also provide the rename command which can be contracted to ren.

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

Example

ren filename newname
ren *.htm *.html

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

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