Hi Istvan, I had the same problem a few months ago, and I discover a shell script that I updated to find identical files in several directories. Unfortunaly I don't remember who the original author his. The script is quite fast once it looks for files with the same size and only then calculates their md5sums. The output is a shell script with all the duplicate files listed, so that you can choose the ones to delete. There is one problem that I could not solve and I don't know the exact reason, but it's related with files with "strange" characters in their names, like "'`'". But this "feature" only manifested once with files that I suspected had Chinese characters in their names. Let me have some feed-back if you use it. Regards Lívio Cipriano ----- Original Message ----- Hello: I'd like to back up my files. I have zillion directories with zillion subdirs and it's possible that some files are duplicated. I would like to find them before backing up. I found a software that can do this but it's not free (zsDuplicateHunter). Do you know one that is opensource and available for suse?
