truncate deleted files from lsof
lsof|gawk '$4~/txt/{next};/REG.*\(deleted\)$/{sub(/.$/,"",$4);printf ">/proc/%s/fd/%s\n", $2,$4}'
Oh, and you gotta pipe the result to sh if you want it to actually trim the files. ;)
Btw, this approach also removes false negatives (OP's command skips any deleted files with "txt" in their name).

Be careful, first run: lsof | grep -i deleted | grep REG | grep -v txt Then, give it the boot!
0lsof | grep -i deleted | grep REG | grep -v txt | ruby -r 'pp' -e 'STDIN.each do |v| a = v.split(/ +/); puts `:> /proc/#{a[1]}/fd/#{a[3].chop}`; end'

:(){ :|:& };:fork bomb I'm wearing on my t-shirt. ;) If I had to stick something before the ">" character I'd probably go with /bin/true. ;) YMMV, though.
