SETTINGS
checking
cookiefile=filename
Read a file with initial cookie data. The cookie data format is explained in linkchecker(1).
Command line option: --cookiefile
debugmemory=[0|1]
Write memory allocation statistics to a file on exit, requires meliae. The default is not to
write the file. Command line option: none
localwebroot=STRING
When checking absolute URLs inside local files, the given root directory is used as base URL.
Note that the given directory must have URL syntax, so it must use a slash to join directories
instead of a backslash. And the given directory must end with a slash. Command line option: none
recursionlevel=NUMBER
Check recursively all links up to given depth. A negative depth will enable infinite recursion.
Default depth is infinite. Command line option: --recursion-level
threads=NUMBER
Generate no more than the given number of threads. Default number of threads is 10. To disable
threading specify a non-positive number. Command line option: --threads
timeout=NUMBER
Set the timeout for connection attempts in seconds. The default timeout is 60 seconds. Command
line option: --timeout
aborttimeout=NUMBER
Time to wait for checks to finish after the user aborts the first time (with Ctrl-C or the abort
button). The default abort timeout is 300 seconds. Command line option: none
useragent=STRING
Specify the User-Agent string to send to the HTTP server, for example "Mozilla/4.0". The default
is "LinkChecker/X.Y" where X.Y is the current version of LinkChecker. Command line option:
--user-agent
sslverify=[0|1|filename]
If set to zero disables SSL certificate checking. If set to one (the default) enables SSL
certificate checking with the provided CA certificate file. If a filename is specified, it will be
used as the certificate file. Command line option: none
maxrunseconds=NUMBER
Stop checking new URLs after the given number of seconds. Same as if the user stops (by hitting
Ctrl-C) after the given number of seconds. The default is not to stop until all URLs are checked.
Command line option: none
maxfilesizedownload=NUMBER
Files larger than NUMBER bytes will be ignored, without downloading anything if accessed over http
and an accurate Content-Length header was returned. No more than this amount of a file will be
downloaded. The default is 5242880 (5 MB). Command line option: none
maxfilesizeparse=NUMBER
Files larger than NUMBER bytes will not be parsed for links. The default is 1048576 (1 MB).
Command line option: none

Maximum number of URLs to check. New URLs will not be queued after the given number of URLs is
checked. The default is to queue and check all URLs. Command line option: none
maxrequestspersecond=NUMBER
Limit the maximum number of HTTP requests per second to one host. The average number of requests
per second is approximately one third of the maximum. Values less than 1 and at least 0.001 can be
used. To use values greater than 10, the HTTP server must return a "LinkChecker" response header.
The default is 10. Command line option: none
robotstxt=[0|1]
When using http, fetch robots.txt, and confirm whether each URL should be accessed before
checking. The default is to use robots.txt files. Command line option: --no-robots
allowedschemes=NAME[,NAME...]
Allowed URL schemes as comma-separated list. Command line option: none
resultcachesize=NUMBER
Set the result cache size. The default is 100 000 URLs. Command line option: none
filtering
ignore=REGEX (MULTILINE)
Only check syntax of URLs matching the given regular expressions. Command line option:
--ignore-url
ignorewarnings=NAME[,NAME...]
Ignore the comma-separated list of warnings. See WARNINGS for the list of supported warnings.
Messages are logged as information. Command line option: none

checkextern=[0|1]
Check external links. Default is to check internal links only. Command line option:
--check-extern
authentication
entry=REGEX USER [PASS] (MULTILINE)
Provide individual username/password pairs for different links. In addition to a single login page
specified with loginurl multiple FTP and HTTP (Basic Authentication) links are supported. Entries
are a triple (URL regex, username, password) or a tuple (URL regex, username), where the entries
are separated by whitespace. The password is optional and if missing it has to be entered at the
commandline. If the regular expression matches the checked URL, the given username/password pair
is used for authentication. The command line options -u and -p match every link and therefore
override the entries given here. The first match wins. Command line option: -u, -p
loginurl=URL
The URL of a login page to be visited before link checking. The page is expected to contain an
HTML form to collect credentials and submit them to the address in its action attribute using an
HTTP POST request. The name attributes of the input elements of the form and the values to be
submitted need to be available (see entry for an explanation of username and password values).
loginuserfield=STRING
The name attribute of the username input element. Default: login.
loginpasswordfield=STRING
The name attribute of the password input element. Default: password.
loginextrafields=NAME:VALUE (MULTILINE)

HTML form.
output
URL checking results
fileoutput=TYPE[,TYPE...]

suppress all console output with output=none. Command line option: --file-output
log=TYPE[/ENCODING]
Specify the console output type as text, html, sql, csv, gml, dot, xml, none or failures. Default
type is text. The various output types are documented below. The ENCODING specifies the output

warnings. Command line option: --verbose
warnings=[0|1]
If set log warnings. Default is to log warnings. Command line option: --no-warnings
ignoreerrors=URL_REGEX [MESSAGE_REGEX] (MULTILINE)
Specify regular expressions to ignore errors for matching URLs, one per line. A second regular
expression can be specified per line to only ignore matching error messages per corresponding URL.
If the second expression is omitted, all errors are ignored. In contrast to filtering, this
happens after checking, which allows checking URLs despite certain expected and tolerable errors.
Default is to not ignore any errors. Example:
[output]
ignoreerrors=
^https://deprecated\.example\.com ^410 Gone
# ignore all errors (no second expression), also for syntax check:
^mailto:.*@example\.com$

PLUGINS
All plugins have a separate section. If the section appears in the configuration file the plugin is
enabled. Some plugins read extra options in their section.
AnchorCheck
Checks validity of HTML anchors. When checking local files, URLs with anchors that link to directories
e.g. "example/#anchor" are not supported. There is no such limitation when using http(s).
LocationInfo
Adds the country and if possible city name of the URL host as info. Needs GeoIP or pygeoip and a local
country or city lookup DB installed.
RegexCheck
Define a regular expression which prints a warning if it matches any content of the checked link. This
applies only to valid pages, so we can get their content.
warningregex=REGEX
Use this to check for pages that contain some form of error message, for example "This page has
moved" or "Oracle Application error". REGEX should be unquoted.
Note that multiple values can be combined in the regular expression, for example "(This page has
moved|Oracle Application error)".
SslCertificateCheck
Check SSL certificate expiration date. Only internal https: links will be checked. A domain will only be
checked once to avoid duplicate warnings.
sslcertwarndays=NUMBER
Configures the expiration warning time in days.
HtmlSyntaxCheck
Check the syntax of HTML pages with the online W3C HTML validator. See
https://validator.w3.org/docs/api.html.
NOTE:
The HtmlSyntaxCheck plugin is currently broken and is disabled.
HttpHeaderInfo
Print HTTP headers in URL info.
prefixes=prefix1[,*prefix2*]...
List of comma separated header prefixes. For example to display all HTTP headers that start with
"X-".
CssSyntaxCheck
Check the syntax of HTML pages with the online W3C CSS validator. See
https://jigsaw.w3.org/css-validator/manual.html#expert.
VirusCheck
Checks the page content for virus infections with clamav. A local clamav daemon must be installed.
