(Bash) Howto run Tidy from the command line - noah

Fri, 05 Feb 2010 12:41:54 GMT

This shell command will retrieve a Web page and validate the HTML with [Tidy, the HTML linter from the W3](http://tidy.sourceforge.net/). You can get an **XHTML validation** report right in your shell prompt, just like you'd get from the [Firefox extension](https://addons.mozilla.org/en-US/firefox/addon/249) or the [Web service.](validator.w3.org/). It's especially helpful when you need to **validate HTML on your intranet, or behind a firewall.** ### **NOTE: Curl does not follow redirects by default!** By default, Curl retrieves *exactly* the URL you specify. The `-L` option causes Curl to follow redirects just like a Web browser would. ### **NOTE: Tidy produces a lot of output!** Windows users should make sure their [command prompt screen buffer height is set to 9999](http://www.codinghorror.com/blog/archives/000334.html 'command prompt tips from Coding Horror') so that you don't "lose" any output. ### **Explanation of the command line options** `curl -L` tells Curl to fo**LL**ow HTTP redirects `curl -s` **S**uppresses Curl's annoying progress bar `tidy -e` tells Tidy not to **E**mit the tidied HTML to the console `tidy -q` tells Tidy to be **Q**uiet, instead of printing extra crap at the bottom of the report ### **Dependencies** Curl and Tidy are installed via the [Cygwin setup.exe](http://cygwin.com/) Alternately, Perl hackers could use [lwp-request](http://search.cpan.org/~gaas/libwww-perl-5.808/bin/lwp-request). ### **Doing more** [Validate HTML with a stricter algorithm,](http://snipplr.com/view/4130/check-linked-pages-for-tidy-validation-errors-on-the-command-line/) using the OpenJade SGML parser. [Validate linked pages](http://snipplr.com/view/4130/check-linked-pages-for-tidy-validation-errors-on-the-command-line/) with Tidy and lwp-request.

(Bash) HTTP Proxy Checker - sensimevanidus

Tue, 04 Aug 2009 17:40:23 GMT

This script tries to detect whether an HTTP Proxy works or not. It uses the HEAD command (high-level version of the lwp-request command) to connect to a given URL (http://www.google.com by default) via the given HTTP Proxy. It takes 2 arguments; the first one is the IP Address or URL of the HTTP Proxy and the second one is its port number. If you have a simpler or faster method, please let me know.

(Bash) check linked pages for Tidy validation errors, on the command line - noah

Tue, 13 Nov 2007 23:47:28 GMT

Given a list of HTML links (for example, a Google results page that has been saved locally) check each link that points to a page on a given domain, and report if Tidy complains that its doctype declaration is missing. Besides DOCTYPE, other strings to search for include "discarding", "lacks value" and "Error:" Remember to replace MY_DOMAIN with the actual domain you want to validate against.
