* To find all files in the `~/html/' directory tree with an `.html' extension, and output lines from these files that contain the string `organic', type:

$ find ~/html/ -name '*.html' -exec grep organic '{}' ';' [RET]

In this example, the command grep organic file is executed for each file that find finds, with file being the name of each file in turn.

To have find pause and confirm execution for each file it finds, use `-ok' instead of `-exec'.

   * To remove files from your home directory tree that were accessed more than one year after they were last modified, pausing to confirm before each removal, type:

$ find ~ -used +365 -ok rm '{}' ';' [RET]
