Specify comma-separated lists of file name suffixes or patterns to accept or reject (see Types of Files). Note that if any of the wildcard characters, ‘*’, ‘?’, ‘[’ or ‘]’, appear in an element of acclist or rejlist, it will be treated as a pattern, rather than a suffix. In this case, you have to enclose the pattern into quotes to prevent your shell from expanding it, like in ‘-A "*.mp3"’ or ‘-A '*.mp3'’.
Specify a regular expression to accept or reject the complete URL.
Specify the regular expression type. Possible types are ‘posix’ or ‘pcre’. Note that to be able to use ‘pcre’ type, wget has to be compiled with libpcre support.
Set domains to be followed. domain-list is a comma-separated list of domains. Note that it does not turn on ‘-H’.
Specify the domains that are not to be followed (see Spanning Hosts).
Follow FTP links from HTML documents. Without this option, Wget will ignore all the FTP links.
Wget has an internal table of HTML tag / attribute pairs that it considers when looking for linked documents during a recursive retrieval. If a user wants only a subset of those tags to be considered, however, he or she should be specify such tags in a comma-separated list with this option.
This is the opposite of the ‘--follow-tags’ option. To skip certain HTML tags when recursively looking for documents to download, specify them in a comma-separated list.
In the past, this option was the best bet for downloading a single page and its requisites, using a command-line like:
wget --ignore-tags=a,area -H -k -K -r http://site/document
However, the author of this option came across a page with tags like
<LINK REL="home" HREF="/"> and came to the realization that
specifying tags to ignore was not enough. One can’t just tell Wget to
<LINK>, because then stylesheets will not be downloaded.
Now the best bet for downloading a single page and its requisites is the
dedicated ‘--page-requisites’ option.
Ignore case when matching files and directories. This influences the behavior of -R, -A, -I, and -X options, as well as globbing implemented when downloading from FTP sites. For example, with this option, ‘-A "*.txt"’ will match ‘file1.txt’, but also ‘file2.TXT’, ‘file3.TxT’, and so on. The quotes in the example are to prevent the shell from expanding the pattern.
Enable spanning across hosts when doing recursive retrieving (see Spanning Hosts).
Follow relative links only. Useful for retrieving a specific home page without any distractions, not even those from the same hosts (see Relative Links).
Specify a comma-separated list of directories you wish to follow when downloading (see Directory-Based Limits). Elements of list may contain wildcards.
Specify a comma-separated list of directories you wish to exclude from download (see Directory-Based Limits). Elements of list may contain wildcards.
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. See Directory-Based Limits, for more details.
