SYNOPSIS

fdupes [ options ] DIRECTORY ...

DESCRIPTION

Searches the given path for duplicate files. Such files are found by comparing file sizes and MD5 signatures, followed by a byte-by-byte comparison.

OPTIONS

-r --recurse
  for every directory given follow subdirectories encountered within
-R --recurse:
  for each directory given after this option follow subdirectories encountered within
-s --symlinks
  follow symlinked directories
-H --hardlinks
  normally, when two or more files point to the same disk area they are treated as non-duplicates; this option will change this behavior
-n --noempty
  exclude zero-length files from consideration
-f --omitfirst
  omit the first file in each set of matches
-1 --sameline
  list each set of matches on a single line
-S --size
  show size of duplicate files
-q --quiet
  hide progress indicator
-d --delete
  prompt user for files to preserve, deleting all others (see CAVEATS below)
-N --noprompt
  when used together with --delete, preserve the first file in each set of duplicates and delete the others without prompting the user
-v --version
  display fdupes version
-h --help
  displays help

SEE ALSO

md5sum(1)

NOTES

Unless -1 or --sameline is specified, duplicate files are listed together in groups, each file displayed on a separate line. The groups are then separated from each other by blank lines.

When -1 or --sameline is specified, spaces and backslash characters (\) appearing in a filename are preceded by a backslash character.

CAVEATS

If fdupes returns with an error message such as fdupes: error invoking md5sum it means the program has been compiled to use an external program to calculate MD5 signatures (otherwise, fdupes uses interal routines for this purpose), and an error has occurred while attempting to execute it. If this is the case, the specified program should be properly installed prior to running fdupes.

When using -d or --delete, care should be taken to insure against accidental data loss.

When used together with options -s or --symlink, a user could accidentally preserve a symlink while deleting the file it points to.

Furthermore, when specifying a particular directory more than once, all files within that directory will be listed as their own duplicates, leading to data loss should a user preserve a file without its "duplicate" (the file itself!).
