Check timestamp of a list of files

[joec]

Hi,
I am new in MS DOS scripting.

Trying to code a script to check and compare time stamp of a list of files. Below is the scripts, but is not working as expected. Need experts' help please.
Thanks a lot.

Line 6 works fine,
Line 7 doesn't work,
Line 8 print fName=null
Line 9 doesn't work,
Line 10 print ftime=null

1  REM===========================
2  SET DIRECTORY=C:\test
3  SET fileList=text1.txt,text2.txt,text3.txt
4  CD %directory% 
5  for %%f in (%fileList%) DO ( 
6   echo %%f found
7   set fName=%%f
8   echo fName=%fName%
9   for %%a in ( %%f ) do set ftime=%%~ta
10   echo ftime=%ftime%
 ... )

Heres a hint, sorry I dont have enough time to rework your problem.

This article describes 'delayed expansion' - it should sort you out

In addition to delayed expansion, it might be wise to check if the file actually exists instead of assuming it does.

Code: [Select]

@echo off
setlocal enabledelayedexpansion
set directory=c:\test
set filelist=text1.txt,text2.txt,text3.txt
cd /d %directory%
for %%f in (%filelist%) do (
  if exist %%f (
    echo %%f found
    set fname=%%f
    echo fname=!fname!
    for %%a in ( %%f ) do set ftime=%%~ta
    echo ftime=!ftime!
  ) else ( echo %%f not found )
) 
endlocal

Good luck.

Joe,
 I could not get  else of if else to work.  I had to use a separate if for the missing files.


C:\test>type sw4.bat

Code: [Select]

@echo off
setlocal enabledelayedexpansion
set directory=c:\test
cd /d %directory%
for /f "delims=" %%i in (text.txt) do (
set filename=%%i
IF EXIST !filename! (
echo file !filename! exists

for %%a in ( %%i ) do set ftime=%%~ta
echo ftime=!ftime!
)
IF not EXIST !filename! echo file !filename! missing
)
Output:

C:\test>sw4.bat
file text.txt exists
ftime=06/08/2010 08:59 PM
file text1.txt exists
ftime=06/08/2010 07:04 PM
file text2.txt exists
ftime=06/08/2010 07:04 PM
file text3.txt exists
ftime=06/08/2010 07:04 PM
file text4.txt exists
ftime=06/08/2010 08:10 PM
file text5.txt   missing
file text77.txt   missing
C:\test>
