Creating batch file to Check Directories

Neablis · 06-16-2009, 10:51 AM

Hello. Im trying to make a batch file that goes through two directors and writes to a txt document all the files that exist in one that dont exist in the other. I have it ALMOST working but i cant figure out how to get it to go down in folders to compare the rest of the directory. Any he[lp would be nice, THANKS!

Code:

@echo off

setlocal ENABLEDELAYEDEXPANSION

Set dirA=%1
Set dirB=%2

dir /B /O %dirA% >dirA.txt
dir /B /O %dirB% >dirB.txt

Echo. >>AnotinB.txt
find /V /C "this_is_an_absurd_string" dirB.txt >numlines.txt
for /f "tokens=3 delims= " %%B in (numlines.txt) do set /A maxnum=%%B

for /F "tokens=* delims= " %%A in (dirA.txt) do (
find /V /C "%%A" dirB.txt >numlines.txt
for /f "tokens=3 delims= " %%B in (numlines.txt) do set /A foundnum=%%B
if %maxnum%==!foundnum! echo %%A >>AnotinB.txt
)


copy /B AnotinB.txt dupli.txt >nul
more dupli.txt

for %%A in (dirA.txt dirB.txt AnotinB.txt numlines.txt) do (
if exist %%A del %%A
)

Welcome to TSF!

The code you posted will display all files that are in DirA that are not in DirB, though it needs some quotes to work with folder names that have spaces:

Code:

dir /B /O        "%dirA%       " >dirA.txt
dir /B /O        "%dirB%       " >dirB.txt

Are you wanting to also compare subfolders? Meaning compare two complete trees, not just the folders?
So not only compare DirA to DirB, but DirA\Sub1 to DirB\Sub1, and DirA\Sub1\SubSub1 to DirB\Sub1\SubSub1?

Or do you just want to find out if a file anywhere in the DirA tree exists anywhere in the DirB tree?
So if File1.txt exists in DirA (DirA\ File1.txt) and is found in DirB\Sub1 (DirB\Sub1\ File1.txt) it would not be listed?

I think i may have got a little further, if not working. Havnt done extensive testing. it leaves the remements of the folder in the search but that can be ignored in my c++ code hats using it. The purpose to find all files that exist in DirA that dont exist in DirB so instead of

Code:

dir /B /O %dirA% >dirA.txt
dir /B /O %dirB% >dirB.txt

Code:

dir /B /O /S %dirA% >dirA.txt
dir /B /O /S %dirB% >dirB.txt

to include all the sub directory's in the search. I saw a lot of people looking for similar stuff when looking for help, so it is working i hope this can help people.

**TheOutcaste** · 06-16-2009, 02:44 PM

That won't work, as the files will contain the full path. Since dirA and dirB are different, it will indicate that all the files in dirA are not in dirB
For example, if test1.txt is in dirA, this will check to see if C:\dirA\test1.txt is found in the listing for dirB. It won't be, as test1.txt will be listed as C:\dirB\test1.txt

You need to remove the root folder from the string you are checking:

Code:

@Echo Off
SetLocal EnableDelayedExpansion
Set dirA=%~1
Set dirB=%~2

Dir /B /O /S "%dirA%">dirA.txt
Dir /B /O /S "%dirB%">dirB.txt

Echo.>>AnotinB.txt
Find /V /C "this_is_an_absurd_string" dirB.txt>numlines.txt
For /F "tokens=3 delims= " %%B In (numlines.txt) Do Set /A maxnum=%%B

For /F "tokens=*" %%A In (dirA.txt) Do (
Set _FN=%%A
Call Set _FN=%%_FN:%dirA%=%%
Find /V /C "!_FN!" dirB.txt>numlines.txt
For /F "tokens=3 delims= " %%B In (numlines.txt) Do Set /A foundnum=%%B
If %maxnum%==!foundnum! Echo %%A>>AnotinB.txt
)
more AnotinB.txt

For %%A In (dirA.txt dirB.txt numlines.txt) Do If Exist %%A Del %%A

Actually its still not working. I can get the recursion working, but not the compare afterwords. Its wierd, im not even sure why its not working anymore, it just writes all the contents to the document.

**TheOutcaste** · 06-16-2009, 03:48 PM

Here's another option. This will be much faster for large directories, as the above version runs the Find command for each file, and has to read the complete DirB.txt file for each file name it checks.

This will list all files that are found in both trees, all files that are in the First tree but not the Second, and all files that are in the Second tree but not the First.

Code:

Thank you Outcaste that script should work perfect for my project.

BTW I Had to add

Code:

if exists duplicat.txt del duplicat.txt

in the code because the results kept getting added together messing with my data.

BTW Its very Elegant code, i like it.

**TheOutcaste** · 06-17-2009, 09:45 AM

You're Welcome!

I didn't use an "If exist delete" statement because the file is automatically deleted on every run when the header is written to the file by this line:

Code:

Echo Files that are found in folder %_DirA% but NOT in folder %_DirB% >duplicat.txt

The single > creates a new file.

Guess I should have used one though, just in case someone doesn't need that header in the output. Thanks for pointing that out.

If your issue has been resolved you can mark this thread Solved by using the Thread Tools at the Top Right of this thread (above the first post)
