find identical files in one or more directory trees

with the free sfk dupfind command for the Windows, Mac OS X, Linux and Raspberry Pi command line.
- download the free Swiss File Knife Base from Sourceforge.
- open the Windows CMD command line, Mac OS X Terminal or Linux shell.
- OS X : type mv sfk-mac-64.exe sfk and chmod +x sfk then ./sfk
- Linux: type mv sfk-linux-64.exe sfk    and chmod +x sfk then ./sfk
  OS X and Linux syntax may differ, check the help within the tool.

sfk dupfind -dir anydir [-file .ext1 .ext2]

find and list duplicate files, just by file content,
independent from filename. searches for files with same
size and then compares contents by md5 checksums.

   -diffdirs    list only duplicates residing in different
                root directories. this option requires that
                you specify at least two dirs after -dir.
   -listorg     list all original filenames,
                leave out any duplicate filenames.
   -minsize=n   compare only files with size >= n.
                examples for n are:
                   5m = 5000000 bytes (5 mbytes)
                 100k =  100000 bytes (5 kbytes)
                   1M = 1048576 bytes (2<<20 bytes)
                9000b =    9000 bytes

command chaining
   - by default, this command passes the names
     of found duplicate files to the next command.

   - option -listorg does the opposite: it passes
     only original filenames, but no duplicates,
     to the next chain command.

   if identical files are found, the decision what is listed
   as "original" or "duplicate" is currently based on the
   order in the file system: the file found first is listed as
   "original". check carefully if this is what you think,
   before cleaning up any duplicates.

web reference

   sfk dupfind .
      find all duplicates within the current directory tree.

   sfk dupfind -dir docs1 docs2 docs3
      find all dups across and within the given directories.

   sfk dupfind -diffdir -dir docs1 docs2 docs3
      find dups between docs1/docs2, docs2/docs3, docs1/docs3,
      but does NOT list dups within the same root directory.

   sfk dupfind docs .doc +del
      find all duplicate .doc files, within the docs
      directory tree, and delete them.

   sfk dupfind -listorg docs .doc +run "copy $file docs2"
      copy all .doc files from docs to docs2,
      but leave out any duplicate files.

   sfk dupfind -dir pic1 -dir pic2 -dir pic3
      find duplicates across three different directory trees.
      specifying multiple -dirs is also a way of influencing
      the result order; if a file is found both in pic1 and pic3,
      the file from pic1 will be listed as original, the other one
      as the duplicate.

   sfk sel -dir pic1 pic2 pic3 -file .jpg +dup -minsize=1m
      similar to the above, this example uses command chaining:
      list all .jpg files from the pic directories, then pass
      this to the dupfind command, also filtering by size.

sfk is a free open-source tool, running instantly without installation efforts. no DLL's,
