rsync to download RFC方法

How to use rsync to download documents from the RFC Editor Repository

[1] To get the list of modules available

type 'rsync ftp.rfc-editor.org::'

This will return a results like following

 (Module Names) (Comments)  everything-ftp Everything FTP rfcs Contents of in-notes/ and subdirectories bcp/, fyi/, ien/, and std/ rfcs-text-only Text files from [rfcs] rfc-ed-all Entire repository (excluding internet-drafts) internet-drafts Internet Drafts ids-text-only Text files from [Internet Drafts] rfcs-pdf-only PDF versions of ASCII RFCs to ensure correct page breaks, etc 

[2] To create a mirror using a module  Type 'rsync -avz --delete ftp.rfc-editor.org::Module-Name Target-Directory'

    Ex) To create a mirror of the text versions of all the RFCs, i.e.,
                             in-notes/*.txt
                             in-notes/bcp/*.txt
                             in-notes/fyi/*.txt
                             in-notes/ien/*.txt
                             in-notes/std/*.txt

        type 'rsync -avz --delete ftp.rfc-editor.org::rfcs-text-only my-rfc-mirror'

(The --delete option is useful for removing local copies of files that have
	been deleted from the repository.  This is helpful to remove expired Internet drafts.)
