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.
