Question

How to rename a file name to a prefix + current date in DOS batch file

Asked by: n_chai

Hi

My machine is an NT.  Everyday, there will be a file (i.e. abc.txt) output to my NT server & I need to write a program (in DOS batch file) to rename the file from abc.txt to abc210300.txt

The 210300 means 21st March 2000, if today is 21/3/2000.  So, everyday the program will be scheduled to run and reanme the abc.txt to

"abc" + current date + ".txt"

This is the batch file commands I have now, but I don't know how to put in the date portion.  

@echo off
echo.

rename c:\temp\abc.txt abc123.txt

@echo off


Thank you.

You will need the help of a tiny program (I can write it for you) to accomplish that job.

Unfortunately, there is no way to do what you need directly from DOS commands; thus, it's impossible to write a .BAT program that make that.

there is no way to write a batch file(*.BAT, with out using some sort of program.

I could wirte the program for you, use some programs i have at home.

you can use the 4NT shell instead of cmd.exe

then you'll be able to do these things.
4NT is available from

Hello
This works for the batch file (.bat) file in MS-DOS on Win2000.

for "abc" + current date + ".txt" you will have to add the code
%date:~4,2%-%date:~7,2%-%date:~10%
at the place you want your current date to appear.

e.g.
ren c:\temp\abc.txt abc%date:~4,2%-%date:~7,2%-%date:~10%.txt

Enjoy :)
