what about the -exec option of find ? I always wonder why people don't
use it.
find . -type f \( -mtime 6 -o -mtime 29 \) -exec vi {} \;
The critical difference is that 'find | xargs foo' runs foo once[*],
to process all the files in one go. 'find -exec foo {}' runs foo one
time for each matched file. In this case, it's probably not a big
deal, but when you need to process hundreds of files 'find | xargs
foo' is much more efficient.
Cheers,
Matthew
[*] Actually, it runs foo repeatedly with as many filenames on the
foo command line as it can each time. That's generally several
hundred files at a go.

Doesn't -xargs prebuffer input via xargs, where -exec does exec on the fly?
