Re: [lesspipe]

[lee.bradshaw@mindspring.com (Lee Bradshaw)]

I really like using a .lesskey file to set up a .less binary
configuration file.  Then you'll have the configuration no matter what
the environment is when you start less.  Here is my .lesskey:


# $Header: /users/bradshaw/RCS/.lesskey,v 1.1 1996/09/21 01:25:38 bradshaw Exp bradshaw $

#env
LESS     = -is
LESSOPEN = |~/.lesspipe.sh %s


The less manpage also shows separate lessopen and lessclose scripts, but
using the pipe above seems to avoid the need for any of the cleanup
provided by lessclose.

Install the file by running "lesskey".  This will create a binary
.less file.  You'll also need something to put in the ~/.lesspipe.sh.
Since you aren't at hamm yet, you might want to try my .lesspipe.sh.
Unfortunately it doesn't handle all the file types mentioned in a
previous message, but you should be able to extend it.  This works for
bash and tcsh, but I haven't tried anything else.


#! /bin/sh

# $Header: /users/bradshaw/bin/RCS/lesspipe.sh,v 1.1 1996/09/21 01:32:37 bradshaw Exp bradshaw $
