fdupes
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 behav-
ior
-n --noempty
exclude zero-length files from consideration
-f --omitfirst
omit the first file in each set of matches
-A --nohidden
exclude hidden files from consideration
-1 --sameline
list each set of matches on a single line
-S --size
show size of duplicate files
-m --summarize
summarize duplicate files information
-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.
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
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 internal 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!).
