You may be wondering what you can do with all these files that you find! Well, find has the ability to act on the files that it finds by using the -exec option. This option accepts a command line to execute as its argument, terminated with ;; and replacing any occurrences of {} with the filename. This is best understood with an example:

$ find /usr/bin -type f -size -50c -exec ls -l '{}' ';'
-rwxr-xr-x    1 root     root           27 Oct 28 07:13 /usr/bin/krdb
-rwxr-xr-x    1 root     root           35 Nov 28 18:26 /usr/bin/run-nautilus
-rwxr-xr-x    1 root     root           25 Oct 21 17:51 /usr/bin/sgmlwhich
-rwxr-xr-x    1 root     root           26 Sep 26 08:00 /usr/bin/muttbug

As you can see, find is a very powerful command. It has grown through the years of UNIX and Linux development. There are many other useful options to find. You can learn about them in the find manual page.
