I have 2 sorted files produced by
xxx>find /store -type f -print | sort > /tmp/invent.txt xxx>find /fbkup -type f -print | sort > /tmp/backup.txt
I want from diff a file name list of files missing in /store which are still on /backup, without any < > annotations, just one output file containing exactly the same records from /tmp/backup for which there was no match on /tmp/invent.txt.
xxx>diff -??? /tmp/invent.txt /tmp/invent.txt | xargs ...
