A huge directory will most definitely > have an issue. In a two-step process, you could do: find . -type f -print0 | \ xargs -0 md5sum | \ sort | \ cut -c1-32 | \ uniq -d (cut will get rid of the path-file-names, which most probably will be different, at least at the path level, and uniq will only list md5sums that appeared more than once). Now, for each line returned, run the find again, this time with a grep; using egrep you could even do this: find . -type f -print0 | \ xargs -0 md5sum | \ sort | \ egrep '(<val1>|<val2>|...)' --Marcin
