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 in bytes

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

       -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)

       -D --deferconfirmation
              in  interactive  mode,  defer  byte-for-byte  confirmation of duplicates until just
              before file deletion

       -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!).
