The non-interactive network downloader
After the download is complete, convert the links in the document to make them suitable for local
viewing. This affects not only the visible hyperlinks, but any part of the document that links to
external content, such as embedded images, links to style sheets, hyperlinks to non-HTML content,
Each link will be changed in one of the two ways:
The links to files that have been downloaded by Wget will be changed to refer to the file they
point to as a relative link.
Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also downloaded, then the
link in doc.html will be modified to point to ../bar/img.gif. This kind of transformation works
reliably for arbitrary combinations of directories.
The links to files that have not been downloaded by Wget will be changed to include host name and
absolute path of the location they point to.
Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to ../bar/img.gif), then
the link in doc.html will be modified to point to http://hostname/bar/img.gif.
Because of this, local browsing works reliably: if a linked file was downloaded, the link will refer
to its local name; if it was not downloaded, the link will refer to its full Internet address rather
than presenting a broken link. The fact that the former links are converted to relative links
ensures that you can move the downloaded hierarchy to another directory.
Note that only at the end of the download can Wget know which links have been downloaded. Because of
that, the work done by -k will be performed at the end of all the downloads.
Continue getting a partially-downloaded file. This is useful when you want to finish up a download
started by a previous instance of Wget, or by another program. For instance:
Turn on options suitable for mirroring. This option turns on recursion and time-stamping, sets
infinite recursion depth and keeps FTP directory listings. It is currently equivalent to -r -N -l
Do not ever ascend to the parent directory when retrieving recursively. This is a useful option,
since it guarantees that only the files below a certain hierarchy will be downloaded.
If a file of type application/xhtml+xml or text/html is downloaded and the URL does not end with the
regexp \.[Hh][Tt][Mm][Ll]?, this option will cause the suffix .html to be appended to the local
filename. This is useful, for instance, when you're mirroring a remote site that uses .asp pages,
but you want the mirrored pages to be viewable on your stock Apache server. Another good use for
this is when you're downloading CGI-generated materials. A URL like http://site.com/article.cgi?25
will be saved as article.cgi?25.html.
Note that filenames changed in this way will be re-downloaded every time you re-mirror a site,
because Wget can't tell that the local X.html file corresponds to remote URL X (since it doesn't yet
know that the URL produces output of type text/html or application/xhtml+xml.
As of version 1.12, Wget will also ensure that any downloaded files of type text/css end in the
suffix .css, and the option was renamed from --html-extension, to better reflect its new behavior.
The old option name is still acceptable, but should now be considered deprecated.
At some point in the future, this option may well be expanded to include suffixes for other types of
content, including content types that are not parsed by Wget.
Set directory prefix to prefix. The directory prefix is the directory where all other files and
subdirectories will be saved to, i.e. the top of the retrieval tree. The default is . (the current
