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.
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
interal 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!).
