Ren (command)
ren (or rename) is a shell command for renaming a file and in some implementations (such as AmigaDOS) a directory.
Some shells with ren also provide a move command that provides for moving between directories. On systems that do not support a move command (such as MS-DOS older than 6.00), the user could copy a file to a new destination and then delete the original file. In DOSBox, ren can move files.
The command is in various shells such as COMMAND.COM, Command Prompt, 4DOS, 4NT and PowerShell. In MS-DOS, the command is available in versions 1 and later. In PowerShell, ren is a predefined alias for the Rename-Item Cmdlet which serves the same essential purpose.
Similar commands are available in many operating systems. The command is available in the CP/M, MP/M, Cromemco DOS, TRIPOS, OS/2, ReactOS, SymbOS, and DexOS. Multics includes a rename command to rename a directory entry; which could be contracted to rn. A rename command which in some cases can be contracted to ren is provided in Stratus VOS, RT-11, OS/8, RSX-11, ISIS-II, iRMX 86, TOPS-20, Z80-RIO, FLEX, OS-9, FlexOS, 4690 OS, MPE/iX, THEOS/OASIS, and OpenVMS A rename command is supported by 86-DOS. DR DOS 6.0 includes ren and rename commands. PC-MOS includes an implementation of rename. It is also available in the MS-DOS emulator DOSBox.
The following renames file foo to bar.
The following renames a file specified by a fully qualified path. The first parameter may contain drive and path information, but the second parameter must be only a file name.
