From time to time I need to do a simple task where I output basic HTML into the console. I'd like to have it minimally rendered, to make it easier to read at a glance. Is there a utility which can handle basic HTML rendering in the shell (think of Lynx-style rendering--but not an actual browser)?

For example, sometimes I'll put a watch on Apache's mod_status page:

watch -n 1 curl http://some-server/server-status

The output of the page is HTML with some minimal markup, which shows in the shell like:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<html><head>
<title>Apache Status</title>
</head><body>
<h1>Apache Server Status for localhost</h1>

<dl><dt>Server Version: Apache/2.2.22 (Ubuntu) PHP/5.3.10-1ubuntu3.15 with Suhosin-Patch</dt>

When viewed in Lynx the same HTML is rendered as: Apache Status (p1 of 2) Apache Server Status for localhost

    Not bash exactly, but check out Xiki, it does that and more – aarosil Nov 20 '14 at 17:15

lynx has a "dump" mode, which you can use with watch:

$ watch lynx https://www.google.com -dump

screenshot of output

From man lynx:

   -dump  dumps  the  formatted  output  of  the default document or those
          specified on  the  command  line  to  standard  output.   Unlike
          interactive mode, all documents are processed.  This can be used
          in the following way:

          lynx -dump http://www.subir.com/lynx.html

          Files specified on the command line are  formatted  as  HTML  if
          their  names  end  with one of the standard web suffixes such as
          “.htm” or “.html”.  Use the -force_html option to  format  files
          whose names do not follow this convention.

This Ask Ubuntu question has many more options.

    lynx is great. it's also a really useful tool when your connection is very bad and you need to go check a site for something - no images, scripts or css makes for a fast page load – jammypeach Nov 20 '14 at 17:58

w3m is another program that has a --dump option.

It is the backend Emacs' most popular web browser.

There are at least two programs named html2text (1) (2) which do this job.

  • Indeed but -- if available -- the output of w3m is much more beautiful esp. for tables. – Suuuehgi Nov 20 '17 at 11:48

elinks has -dump mode too

elinks -dump https://www.google.com
  • See also links on which elinks is based. Same command works... – user44370 Nov 20 '14 at 6:51
