13 Almost right.
14
15 -exec + will not append all filenames found and run one command,
16
17 it will append the maximum number of filenames that do not exceed the shell
18 command line limit, and do that enough times to get through all the filenames.
19
20 You will be surprised how easy it is to get a directory with enough files in
21 it to exceed the shell command length limit (65535 chars?). I have several
22 users who will gladly show you how it's done, and will show you where they
23 have each done it in multiple places
