Re: any program that search for same files?

according to rdfind manual:

       Search for duplicate files in home directory and a backup directory:
              rdfind ~ /mnt/backup

i run "rdfind /mnt/money/doc /mnt/play"
to my alarm, it delete files:

Now scanning "/mnt/money/doc", found 925 files.
Now scanning "/mnt/play", found 30527 files.
Now have 31452 files in total.
Removed 0 files due to nonunique device and inode.
Now removing files with zero size from list...removed 1 files
Total size is 30245034596 bytes or 28 Gib
Now sorting on size:removed 18727 files due to unique sizes from list.12724 files left.
Now eliminating candidates based on first bytes:^C

fdupes or jdupes fit the bill.
