Description:
I want to use a syntax like COMP I:\folder1 Z:\folder2 to compare all files in my I drive with the content of my z drive. I only need to compare their names to see if one exsists in the other. I need to recurse into the subdirectories because there are many located in both drives, I understand I need to use a batch script using a FOR loop and the PUSHD and POPD command.
QUESTION:
How do I do this?
From the output from FOR /?
FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]
Walks the directory tree rooted at [drive:]path, executing the FOR
statement in each directory of the tree. If no directory
specification is specified after /R then the current directory is
assumed. If set is just a single period (.) character then it
will just enumerate the directory tree.
So you'd do something like
@echo off
setlocal enabledelayedexpansion ENABLEEXTENSIONS
for /R P:\ %%F in (*.*) DO (
set fileFull=%%~fF
set filePath=%%~pF
set fileDrive=%%~dF
set fileName=%%~nF
set fileExtension=%%~xF
call :checker "!filePath!" "!fileName!" "!fileExtension!"
)
goto :eof
:checker
set fileTarget="c:%~1%~2%~3"
if not exist %fileTarget% echo %fileTarget% not found
goto :eof
In this case, the script is getting all the filenames in P:\ and its subdirectories and telling me if the file doesn't exist on the same path in C:
List folder differences over a tree:
This uses robocopy to create the list - don't remove /L as this switch makes robocopy only list the information.
robocopy "d:\source\folder one" "c:\target\folder two" /L /fp /njs /njh /ndl /ns /np /mir
If you really need to avoid third party utilities:
@ECHO OFF
SET FOLDER1=I:\Folder1\
SET FOLDER2=Z:\Folder2\
ECHO SET FNAME=%%1 ^& @ECHO %%FNAME:%FOLDER1%=%%^>^>FILES1.TXT>FILES1.BAT
ECHO SET FNAME=%%1 ^& @ECHO %%FNAME:%FOLDER2%=%%^>^>FILES2.TXT>FILES2.BAT
IF EXIST FILES1.TXT DEL FILES1.TXT
IF EXIST FILES2.TXT DEL FILES2.TXT
FOR /F "tokens=*" %%* IN ('DIR /S /B /ON "%FOLDER1%"') DO CALL FILES1.BAT "%%*"
FOR /F "tokens=*" %%* IN ('DIR /S /B /ON "%FOLDER2%"') DO CALL FILES2.BAT "%%*"
ECHO Files from "%FOLDER1%" which are not found in "%FOLDER2%"
FOR /F "tokens=*" %%* IN (FILES1.TXT) DO (FIND %%* FILES2.TXT >NUL || ECHO %%*)
ECHO Files from "%FOLDER2%" which are not found in "%FOLDER1%"
FOR /F "tokens=*" %%* IN (FILES2.TXT) DO (FIND %%* FILES1.TXT >NUL || ECHO %%*)
