fdupes is a simple Command Line utility to find and list duplicate files in the specified directories. fdupes can also delete the found duplicate files if instructed. fdupes can follow Symlinks and can be instructed to ignore hardlinks. fdupes can also show the size of the duplicate files.
fdupes is a simple and very efficient tool, easy to use.

opensuse11:~ # which fdupes
To simply find the duplicate files in a directory, run fdupes with the name of the directory that it should search as follows
opensuse11:~ # fdupes ~saibaba/Documents/
There you can see it has found two files that has a duplicate.
To show the duplicate files on the same line use the “–sameline” arguement
opensuse11:~ # fdupes –sameline ~saibaba/Documents/
To delete duplicate files, use the “-d” or “–delete” arguement. fdupes will prompt you to choose the file(s) to preserve.
opensuse11:~ # fdupes -d ~saibaba/Documents/
Set 1 of 2, preserve files [1 – 2, all]: 2
Set 2 of 2, preserve files [1 – 2, all]: 2
For more customizable options, use the “–help” or “-h” arguement or the man pages for fdupes (“man fdupes”)
opensuse11:~ # fdupes -h
Usage: fdupes [options] DIRECTORY…
-r –recurse include files residing in subdirectories
-s –symlinks follow symlinks
-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
-n –noempty exclude zero-length 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
-q –quiet hide progress indicator
-d –delete prompt user for files to preserve and delete all
others; important: under particular circumstances,
data may be lost when using this option together
with -s or –symlinks, or when specifying a
particular directory more than once; refer to the
fdupes documentation for additional information
-v –version display fdupes version
