Question

Batch file to change file name

Asked by: kg6lfz

I like to create a batch file, so that a file name will have datestamp in it.  I created one but Year does not appear in file name.  Also, I would like to add 4-digit timestamp and delete "-", so that file name looks like preinv_200801222230.txt.

My batch file reads:
@echo off

set thedate=%date%
set yyyy=%thedate:~7,4%
set mm=%thedate:~11,2%
set dd=%thedate:~13,2%

copy PREINV.txt preinv_%yyyy%%mm%%dd%.txt

This produces "preinv_01-22.txt" as a file name.  Can somebody tell me where the problems are and modify my statement?

I appreciate your suggestions in advance.  Thank you.

Try following if this works...

@echo off
set thedate=%date% %time%
ECHO %thedate%
set yyyy=%thedate:~10,4%
set mm=%thedate:~4,2%
set dd=%thedate:~7,2%
set hh=%thedate:~15,2%
set mi=%thedate:~18,2%
copy PREINV.txt preinv_%yyyy%%mm%%dd%%hh%%mi%.txt

Thank you for your quick suggestions.  I copied and pasted it and run the batch.  But it did not generate any file.  I did not mentioned before, but my O/S is Japanese.  Does it make any difference?

Do you have any ideas why it did not work for me?

Thank you very much in advance.

Addition to my comment earlier,

My O/S = Japanese Win 2K.  Date format in Regional settings = yyyy-MM-dd
I would like to change file name PREINV.txt to PREINV_yyyymmddhhss.txt using BAT file.
The script from "farhankazi" did not work.  (Nothing got generated.)  Any ideas?  Thank you in advance.

I run this script from "FARHANKAZI" on English O/S and bingo!  It worked greate just as I wanted.  Thank you "FARHANKAZI".  But the same script does not work on Japanese O/S.  My Time Zone for reginal setting is set as "GMT-08:00" PST time.  Does anybody know how to standardize date/time, so that I can get date/time in PST time zone or is there way to convert from Japanese date/time to English date/time?

Sorry for asking so many times, but I appreciate your suggestions.  Thank you all.

Based on "farhankazi" script, I modified it as indicated below.  This returns the file name with "preinv_200801241403" datestamp when the script is run on Japanese O/S.  Thank you "farhankazi"!  You lead me to a right direction.
