.TH "webcheck" "1" "Jul 2005" "Version 1.9.4" "User Commands"
.nh
.SH "NAME"
webcheck \- website link checker
.SH "SYNOPSIS"
.B webcheck
.RI [ OPTION ]...
.I URL
.SH "DESCRIPTION"
\fBwebcheck\fP will check the document at the specified URL for links to other documents,
follow these links recursively and generate an HTML report.
.TP
.BI \-x " PATTERN"
Mark URLs matching the
.I PATTERN
(perl\-type regular expression) as an external link.
Can be used multiple times.
Note that the PATTERN is matched against the full url.
.TP
.BI \-y " PATTERN"
Do not check URLs matching the
.I PATTERN
(perl\-type regular expression).
Like the \-x flag, though this option will cause webcheck to not
check the link matched by regex whereas \-x will check the link but
not its children.
Can be used multiple times.
Note that the PATTERN is matched against the full url.
.TP
.B \-b
Consider any URL not starting with the base URL to be external.
For example, if you run
.ft B
webcheck \-b http://www.example.com/foo
.ft R
.br
then http://www.example.com/foo/bar will be
considered internal whereas http://www.example.com/ will
be considered external.
By default all the pages on the site will be considered internal.
.TP
.B \-a
Avoid external links.
Normally if webcheck is examining an HTML page
and it finds a link that points to an external document, it will
check to see if that external document exists.
This flag disables that action.
.TP
.B \-q, \-\-quiet, \-\-silent
Do not print out progress as webcheck traverses a site.
.TP
.B \-d, \-\-debug
Print debugging information while crawling the site.
This option is mainly useful for developers.
.TP
.BI \-o " DIRECTORY"
Output directory. Use to specify the directory where webcheck will
dump its reports. The default is the current directory or as
specified by config.py. If this directory does not exist it will
be created for you (if possible).
.TP
.B \-f, \-\-force
Overwrite files without asking.
.TP
.BI \-r " N"
Redirect depth. the number of redirects webcheck should follow when
following a link. 0 implies to follow all redirects.
.TP
.BI "\-w, \-\-wait=" "SECONDS"
Wait
.I SECONDS
between document retrievals. Usually webcheck will process a url
and immediately move on to the next. However on some loaded
systems it may be desirable to have webcheck pause between requests.
This option can be set to any non\-negative number.
.TP
.B \-v, \-\-version
Show version of program.
.TP
.B \-h, \-\-help
Show short summary of options.
.SH "EXAMPLES"
Check the site www.example.com but exclude any path with "/webcheck" in it.
.ft B
webcheck http://www.example.com/ \-x /webcheck
.ft R
.SH "NOTES"
When checking internal urls webcheck honors the robots.txt file, identifying
itself as user-agent webcheck. Disallowed links will not be checked at all as
if the -y option was specified for that url. To allow webcheck to crawl parts
of a site that other robots are disallowed, use something like:
.ft B
User-agent: *
Disallow: /foo
User-agent: webcheck
Allow: /foo
.ft R
.SH "ENVIRONMENT"
.TP
.BI <scheme>_proxy
Proxy url for <scheme>.
.SH "REPORTING BUGS"
Bug reports shoult be sent to the current maintainer <arthur@ch.tudelft.nl>.
More information on reporting bugs can be found on the webcheck homepage:

http://ch.tudelft.nl/~arthur/webcheck/
There is an old known issue with IIS that under some conditions seems te
return illegal return codes. Since much of the HTTP core of webcheck
has been rewritten it is likely that this is no longer uccurs. This problem
can sometimes be worked around by adding "\-y /_" to the webcheck command.
