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
