NAME

SYNOPSIS

DESCRIPTION

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

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 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!).
