To use a proxy set $http_proxy, $https_proxy, $ftp_proxy, $gopher_proxy

The most common use checks the given domain recursively, plus any
single URL pointing outside of the domain:
linkchecker http://treasure.calvinsplayground.de/
Beware that this checks the whole site which can have several hundred
thousands URLs. Use the -r option to restrict the recursion depth.
Don't connect to mailto: hosts, only check their URL syntax. All other
links are checked as usual:
linkchecker --ignore-url=^mailto: www.mysite.org
Checking a local HTML file on Unix:
linkchecker ../bla.html
Checking a local HTML file on Windows:
linkchecker c:\temp\test.html
You can skip the "http://" url part if the domain starts with "www.":
linkchecker www.myhomepage.de
You can skip the "ftp://" url part if the domain starts with "ftp.":
linkchecker -r0 ftp.linux.org

Note that by default only errors and warnings are logged.
You should use the --verbose option to get the complete URL list,

text Standard text output, logging URLs in keyword: argument fashion.
html Log URLs in keyword: argument fashion, formatted as HTML.
Additionally has links to the referenced pages. Invalid URLs have
HTML and CSS syntax check links appended.
csv Log check result in CSV format with one URL per line.
gml Log parent-child relations between linked URLs as a GML sitemap
graph.
dot Log parent-child relations between linked URLs as a DOT sitemap
graph.
gxml Log check result as a GraphXML sitemap graph.
xml Log check result as machine-readable XML.
sql Log check result as SQL script with INSERT commands. An example
script to create the initial SQL table is included as create.sql.
blacklist
Suitable for cron jobs. Logs the check result into a file
~/.linkchecker/blacklist which only contains entries with invalid
URLs and the number of times they have failed.
none Logs nothing. Suitable for debugging or checking the exit code.
