Directory Comparer?

Does anyone know of a good tool to compare two directories and tell me the differences between them? I've got a couple of directories, each with about 3,000 pictures in them (convienienty named DSC_****.JPG) that are about 95% the same. I want something to quickly tell me what files are in one that aren't in the other. I could probably whip up a quick UNIX shell script, except that this is a Windows box. Google brought up the usual list of generic spyware that I don't particularly trust. Anyone know of anything that might do what I need?

Oh, and all I need it to compare is filenames. It doesn't need to, and in fact should NOT check if the files themselves are identical (which is part of why I can't use rsync).

I have used windiff in the past. It is part of windows support tools and you can download it at the following address

Cool. Thanks. I ended up just booting into Gentoo and writing a shell script after all. I gave in. That tool could have been useful, however.

Thanks for the link! Now I know that my copy of the WinXP Pro CD is better than the other downloaded versions (except that it's not bootable!).

Might you post that here? I'm curious how you went about it, since I can't figure much of an idea for it, and this would be useful.

If you don't mind, of course.

You could have used CygWin for POSIX emulation. Great for having a unix environment on your windows system.

Can't you just use the "diff" command? For example, when I enter:

diff /home/tkang /home/tkang/J2Rev.0.2

I get

Only in /home/tkang: .bash_history
Only in /home/tkang: .bash_profile
...
Only in /home/tkang/J2Rev.0.2: Getstring.h
etc...

You can also use it to compare files as well.

The version I wrote was just a simple thing which essentially mixed "for i in '(ls -A $1)']; do" with "if [-e $2/$i]". It didn't check for subdirectories, symbolic links, or any of the other obvious error checking that a truly useful script would since it was just a one-time thing.

However, a quick bit of Googling found cmptree, which is kind of what I wanted except on steroids.

function gettype () {
  if [ -L $1 ]; then
    echo "softlink"
  elif [ -f $1 ]; then
    echo "file"
  elif [ -d $1 ]; then
    echo "directory"
  else
    echo "unknown"
  fi
}

function exists () {
  if [ -e $1 -o -L $1 ]; then
    return 0;
  else
    echo "$1 does not exist."
    return 1;
  fi
}

function comparefile () {
  cmp -s $1 $2
  if [ $? -gt 0 ]; then
    echo "$1 different from $2"
#  else
#    echo "$1 same as $2"
  fi
  return
}

function comparedirectory () {
  local result=0
  for i in `(ls -A $1 && ls -A $2) | sort | uniq`; do
    compare $1/$i $2/$i || result=1
  done
  return $result
}

function comparesoftlink () {
  local dest1=`ls -l $1 | awk '{ print $11 }'`
  local dest2=`ls -l $2 | awk '{ print $11 }'`

  if [ $dest1 = $dest2 ]; then
    return 0
  else
    echo "different link targets $1 -> $dest1, $2 -> $dest2"
    return 1
  fi
}

# compare a file, directory, or softlink
function compare () {
  (exists $1 && exists $2) || return 1;

  local type1=$(gettype $1)
  local type2=$(gettype $2)

  if [ $type1 = $type2 ]; then
    case $type1 in
      file)
        comparefile $1 $2
        ;;
      directory)
        comparedirectory $1 $2
        ;;
      softlink)
        comparesoftlink $1 $2
        ;;
      *)
        echo "$1 of unknown type"
        false
        ;;
    esac
  else
    echo "type mismatch: $type1 ($1) and $type2 ($2)."
    false
  fi

  return
}

if [ 2 -ne $# ]; then
cat << EOU
Usage: $0 dir1 dir2
Compare directory trees:
  files are binary compared (cmp)
  directories are checked for identical content
  soft links are checked for identical targets
EOU
  exit 10
fi

compare $1 $2
exit $?

here's a rough command that could be used in the console in windows to tell what files in the source folder are or aren't in the destination folder and dump whether or not they filecompare as the same file as well. I think it gets rather spammy though if files don't compare exactly.

it would be run from the source directory and tmp2 would need to be replaced with the target directory.

for %i in ( *.* ) do if exist "tmp2\%i" (fc %i tmp2\%i >> Filecompare.txt ) else echo
File tmp2\%i not found >> FileNOTFound.txt

ah the good old days before GUI's did all this crap.
