Are there any programs that can help identify files and directories belonging to unfinished bittorrent-downloads?  I've made a mess, and I'm unsure of which downloads are finished and which are not.  I could obviously use the bt-client, if I still had the torrent-files, but I don't.  I'm therefor looking for way to identify likely unfinished bt-downloads - doesn't have to be 100% accurate.I've noticed that bt-clients typically create empty-files, as well as leave files with holes (blocks of the file with just NULL-characters), so this could perhaps be a good way to find likely candidates.  Sadly, I don't know any good Linux-commands for finding files with blocks of NULLs...
Program for identifying files from unfinished torrent-downloads?

If your grep supports it; you could do a check by grep.grep -P '\x00{NNN}' FileWhere NNN is how many continuously zero bytes you want to match. Would typically be max USHRT_MAX or 65535.-P is needed to use \x00To list offsets use:grep -Pboa '\x00{NNN}' FileSo something in the direction of:for f in *; do    [ -e $f ] || break    if grep -Pq '\x00{1000}' $f; then         mv $f ../likely_corrupt    fidoneElse you could use hexdump, xxd or the like and match for 000....hexdump -ve '/1 %02X'But that would be crazy slow.Finally a very short C program could do the same.
