Microsoft DOS ren and rename
Used to rename files and directories from the original name to a new name.
In earlier releases of MS-DOS instead of using ren or rename you need to use the move command to rename your MS-DOS directories or files.
The ren and rename commands are internal commands that are available in the below Microsoft operating systems.
Renames a file/directory or files/directories.
RENAME [drive:][path][directoryname1 | filename1] [directoryname2 | filename2]
REN [drive:][path][directoryname1 | filename1] [directoryname2 | filename2]
Note that you cannot specify a new drive or path for your destination.
rename c:\computer hope
Rename the directory computer to hope.
rename *.txt *.bak
Rename all text files to files with .bak extension.
rename * 1_*
Rename all files to begin with 1_. The asterisk (*) in this example is an example of a wild character; because nothing was placed before or after the first asterisk, this means all files in the current directory will be renamed with a 1_ in front of the file. For example, if there was a file named hope.txt it would be renamed to 1_pe.txt.
rename "computer hope.txt" "example file.txt"
Rename the file "computer hope.txt" to "example file.txt". Whenever dealing with a file or directory with a space, it must be surrounded with quotes. Otherwise you'll get the "The syntax of the command is incorrect." error.
