Hi
Today is my first day in Batch Scripting, I got an issue which I want to share with you all
I have a text files in my directory. I Want to write a batch script which changes the name and add date stamp to it
For example -
1.txt - > should be renamed to -> 1_09_05_2013_.txt (1_mm_dd_yyyy_.txt)
Regards
Parth

This is how far I got... Maybe it'll be enough to help you out. I'll try and finish it...
Code: Select all
@echo off
setlocal enabledelayedexpansion
for /f "tokens=*" %%F in ('dir /b /a-d') do echo %%~nF>> temp.tmp
<temp.tmp (
for /f "tokens=1-3 delims=." %%A in ('forfiles /c "cmd /c echo @fdate"') do (
set /p fname=
echo !fname!_%%A_%%B_%%C_
)
)
del temp.tmp

This works now, however it also "works" the files created by the script itself, so still some work to do...
Code: Select all
@echo off
setlocal enabledelayedexpansion
for /f "tokens=*" %%F in ('dir /b /a-d') do echo %%~nF>> temp.tmp
<temp.tmp (
for /f "tokens=1-3 delims=." %%A in ('forfiles /c "cmd /c echo @fdate"') do (
set /p fname=
echo !fname!_%%A_%%B_%%C_>>temp2.tmp
)
)
<temp2.tmp (
for /f "tokens=*" %%X in ('dir /b /a-d') do (
set /p tname=
echo %%X !tname!>>cmd.tmp
)
)
<cmd.tmp (
for /f "tokens=*" %%Z in ('dir /b /a-d') do (
set /p cmd=
ren !cmd!%%~xZ
)
)
del temp.tmp
del temp2.tmp
del cmd.tmp

Haha, only now I see that all your files are *.txt, so fixed:
Code: Select all
@echo off
setlocal enabledelayedexpansion
for /f "tokens=*" %%F in ('dir *.txt /b /a-d') do echo %%~nF>> temp.tmp
<temp.tmp (
for /f "tokens=1-3 delims=." %%A in ('forfiles /c "cmd /c echo @fdate"') do (
set /p fname=
echo !fname!_%%A_%%B_%%C_>>temp2.tmp
)
)
<temp2.tmp (
for /f "tokens=*" %%X in ('dir *.txt /b /a-d') do (
set /p tname=
ren %%X !tname!.txt
)
)
del temp.tmp
del temp2.tmp

The user did not specify what date stamp they wanted. Created date. Modified date. Today's date.
If the user wanted modified date there is no need to use the temp file and extra loops you have. You can just use the DATE Modifier %~tI.
What do you think will happen if a new text file is created in the directory in between your loops?

and why a temp file and why forfiles?

It's what I know and what works. You both can post your solutions, if I may say so...
I never said it was optimal, but since no one has answered so far, I did my best.
As for %~t, I have tried with that, but I couldn't separate time from the date so to only use date; like I said, anyone with comments is welcome to post their solution.

Until someone creates a text file while your batch file is running.

I won't do anything until I have all the details of a problem. Coding for Created Date, Modified Date and Today's date are all completely different.

parthmittal2007 should really specify what he means by date. Like Squashman mentioned - are we talking about creation date of the file or last access date or last written date or maybe even just current date?
parthmittal2007 - I'm awaiting for your clarification.
In the meanwhile something more to play with:
Code: Select all
@echo off
for /f "tokens=1-3 delims= " %%X in ('dir *.txt /a-d ^| find ^":^" ^| find /V ^"^\^"') do echo %%X

Like your last code that still gets the modified date. You have to use /TC to get the created date.

Yes, I know... I'm still learning and I have fun doing this, so I try all scenarios - for fun.
And because I was playing around again, I didn't wait for Parth to specify what date he wants, here's code which takes today's date and embeds it in the filename. :p
Code: Select all
@echo off
for /f "tokens=2 delims= " %%X in ('date /T') do set todayd=%%X
for /f "tokens=1-3 delims=." %%F in ("%todayd%") do set todayd=_%%F_%%G_%%H_.txt
for /f "tokens=*" %%K in ('dir *.txt /b /a-d') do ren %%K %%~nK%todayd%

I posted a /tc solution

This is my version:
Code: Select all
@echo off
setlocal EnableDelayedExpansion
set whichDate=date:/=_
if "%1" neq "" set whichDate=fileDate
for /F "tokens=1,4*" %%a in ('dir /A-D /T%1 *.txt') do (
set fileDate=%%a
set fileDate=!fileDate:/=_!
if "!fileDate!" neq "%%a" (
ECHO ren "%%c" "%%~Nc_!%whichDate%!_%%~Xc"
)
)
Place in first parameter the first letter of the desired date: Creation, Access or Written. For example, for last Access date:
If no parameter is given, current date is used.

It looks like my 24 time confuses it in my locale settings.
My file is called "a good dog.txt" and this is printed.
ren "good dog.txt" "good dog_10_05_2013_.txt"
