NAME

       fdupes - finds duplicate files in a given set of directories

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 (note the  ':'
              at the end of option; see the Examples section below for further explanation)

       -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

       -G --minsize=SIZE
              consider only files greater than or equal to SIZE

       -L --maxsize==SIZE
              consider only files less than or equal to SIZE

       -n --noempty
              exclude zero-length files from consideration

       -A --nohidden
              exclude hidden 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

       -t --time
              show modification time of duplicate files

       -m --summarize
              summarize duplicate file information

       -q --quiet
              hide progress indicator

       -d --delete
              prompt user for files to preserve, deleting all others (see CAVEATS below)

       -P --plain
              with --delete, use line-based prompt (as with older versions of  fdupes)  instead  of  screen-mode
              interface

       -N --noprompt
              when used together with --delete, preserve the first file in each set of duplicates and delete the
              others without prompting the user

       -I --immediate
              delete duplicates as they are encountered, without grouping into sets; implies --noprompt

       -p --permissions
              don't consider files with different owner/group or permission bits as duplicates

       -o --order=WORD
              order  files  according  to  WORD: time - sort by modification time, ctime - sort by status change
              time, name - sort by filename

       -i --reverse
              reverse order while sorting

       -l --log=LOGFILE
              log file deletion choices to LOGFILE

       -v --version
              display fdupes version

       -h --help
              displays help

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.

EXAMPLES

       fdupes a --recurse: b
              will follow subdirectories under b, but not those under a.

       fdupes a --recurse b
              will follow subdirectories under both a and b.

CAVEATS

       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!).
