FDUPES(1)                   General Commands Manual                  FDUPES(1)

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 to‐
       gether 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 acci‐
       dental data loss.

       When  used together with options -s or --symlink, a user could acciden‐
       tally 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  "dupli‐
       cate" (the file itself!).
