Directory diff with text file output

Question

It appears I was unable to save the scripts I used for converting some Subversion repos to Mercurial ones, more specifically the filemaps.

How can I get diffs between two directories (added/removed directories, files, etc.) with the results provided in a text file?

Answer 1

Using a full-fledged diff tool like diffmerge or kdiff3 (both free) you can easily check the differences by comparing the output files of the following batch file. As it is, you need to provide the two directories as arguments, but you may as well set those directly in the SET dir... lines - e.g. SET dir1=c:\svn and SET dir2=c:\hg. The script removes the path prefix from the filenames which would otherwise differ on all lines.

@ECHO OFF
SetLocal EnableDelayedExpansion
SET dir1=%1
SET dir2=%2
ECHO. 2>dir1.txt
ECHO. 2>dir2.txt
FOR /f "tokens=*" %%F IN ('DIR /s /b /o:n %dir1%') DO ( 
    SET tmp=%%F
    ECHO !tmp:%dir1%\=! >> dir1.txt
)
FOR /f "tokens=*" %%F IN ('DIR /s /b /o:n %dir2%') DO ( 
    SET tmp=%%F
    ECHO !tmp:%dir2%\=! >> dir2.txt
)
EndLocal

Then just diff the two output files dir1.txt and dir2.txt:

kdiff3 dir1.txt dir2.txt
