I am looking for a way to search for a determinate file in OSX (Maverick but more generally OSX).
In particular I would like to do the following:
given a File_001 I'd like to search if in the filesystem exists a copy of this file.
Not just with the same name, I would like the comparison method to be an hashing algorithm like MD5, SHA etc..
Most of the "duplicate file finder" I have tried just search for all the duplicates in a drive/system. I would, instead, be interested in submitting one file and search for its duplicates.
Does anyone know if such a program exists? Maybe some obscure function of Spotlight?

You might also use
fdupes
. It doesn't have an option to search for duplicates of a specific file, but you can just grep the output for the filename:-r
recurses into directories and-1
prints each group of duplicate files on a single line.Other useful examples:
fdupes -r .
finds all duplicate files under the current directory;fdupes -r . -dN
deletes all except the first duplicate from each group of duplicates;fdupes -r dir1 dir2|grep dir1/|xargs rm
removes duplicates indir1
.You can install
fdupes
withbrew install fdupes
.
