CHKLINKS(1) User Contributed Perl Documentation CHKLINKS(1)NAMEchklinks - A non-threaded Perl link checker
SYNOPSISchklinks [options] URL1 [URL2 [UR3 ...]]
DESCRIPTIONchklinks is a non-threaded Perl link checker. It helps finding broken
links on your website.
chklinks differs from "linkchecker" in that chklinks is non- threaded.
It does not raises many simultaneously connections for its job. It
won't run out of the resources and crash your system in a moment. This
is certainly more desirable for most webmasters and users.
chklinks follows robots.txt rules. If you disallow robots from your
website and experience problems, you need to allow chklinks. Add the
following lines to your robots.txt file to allow chklinks:
User-agent: chklinks
Disallow:
chklinks uses LWP::RobotUA(3) and support the following schemes: http,
https, ftp, gopher and file. You can also specify a local file. (To
use https, you need to install Crypt::SSLeay(3). This is the
requirement of LWP::RobotUA(3).)
chklinks supports cookies.
OPTIONS-1,--onelevel
Check the links on this page and stops.
-r,--recursive
Recursively check through this website. This is the default.
-b,--below
Only check the links below this directory. This is the default.
-p,--parent
Trace back to the parent directories.
-l,--local
Only check the links on this same host.
-s,--span
Check the links to other hosts (without recursion). This is the
default.
-e,--exclude path
Exclude this path. Check for their existence but not check the
links on them, just like they are on a foreign site. Multiple
"--exclude" are OK.
-i,--include path
Include this path. An opposite of "--exclude" that cancels its
effect. The latter specified has a higher priority.
-d,--debug
Display debug messages. Multiple "--debug" to debug more.
-q,--quiet
Disable debug messages. An opposite that cancels the effect of
"--debug".
-h,--help
Display the help message and exit.
-v,--version
Output version information and exit.
URL1, URL2, URL3
The URLs of the websites to check against.
NOTESchklinks does not obey "Crawl-delay:" in robots.txt yet. This is a
problem in WWW::RobotRules(3), but not chklinks itself.
If you encounter warnings like this:
Parsing of undecoded UTF-8 will give garbage when decoding
entities at /usr/share/perl5/LWP/Protocol.pm line 114.
This is a LWP::Protocol(3) issue when working with HTML::Parser(3)
version >= 3.40. See CPAN RT Bug#20274
http://rt.cpan.org/Public/Bug/Display.html?id=20274 for a
LWP::Protocol(3) patch on this.
BUGSchklinks does not support authentication yet. W3C-LinkChecker have
support on this. As a workaround, You can use the syntax
http://user:pass@some.where.com/some/path for Basic Authentication, but
this does not work on Digest Authentication. This practice is not
encouraged. Your password would be visable to anyone on this system
using ps, including hidden intruders. Also what you type in your shell
will be saved to your shell history file.
"mailto:" URLs should be supported by checking the validity of its
DNS/MX record. Bastian Kleineidam's linkchecker(1) have support on
this.
Local file checking has only been tested on Unix and MSWin32. More
platforms should be tested, especially VMS and Mac.
