On my system, I get this as the lesspipe help message:

#########################################
[paulcol@bluering ~]
[Sun May 13 10:26:09]$ lesspipe --help
lesspipe: preproccess files before sending them to less

Usage: lesspipe <file>

lesspipe specific settings:
LESSCOLOR env - toggle colorizing of output (no/yes/always)
LESSCOLORIZER env - program used to colorize output (default:
code2color)
LESSIGNORE - list of extensions to ignore (don't do anything
fancy)

You can create per-user filters as well by creating the executable file:
~/.lessfilter
One argument is passed to it: the file to display.

To use lesspipe, simply add to your environment:
export LESSOPEN="|lesspipe %s"

Run 'less --help' or 'man less' for more info
#########################################

I would interpret the "don't do anything fancy" caveat on LESSIGNORE to mean
that wildcards may not work. Some experimenting on my system shows me that
this version seems to do what you want:

LESSIGNORE="htm html"

I don't normally have LESSOPEN set, so I havn't seen this situation before.

Before you criticize someone, you should walk a mile in their shoes.
Then, when you do, you'll be a mile away, and you'll have their shoes.

Blimey! Thank you! That's wonderful!
