HOWTO

# less 406
# ========
# Slackware 8.1's 'less' package includes version 374, 9.0 and 9.1's include
# 381, 10.0, 10.1, and 10.2's include 382, and 11.0's and 12.0's include 394
#
# 9.0 and up include a lesspipe.sh script written by Patrick Volkerding
# (the author of Slackware).  Below I include a different one with support
# for more types of files (more as of the last time I checked).

# If you ever want to uninstall less, or clean up files from an old version
# before installing a new one, skip down to the bottom for instructions.

# Prerequisites:
# grep
# ncurses

# lesspipe 1.53
# =============
# lesspipe.sh is a script that less can use to let you do funky things like
# this:
#   less ~/tarball.tar.bz2
# (that does the same as running 'tar tjvf ~/tarball.tar.bz2 | less')

# Prerequisites (AFAIK all optional):
# file
# zsh
# ksh
# lsbom (I think this is an Apple util)
# bzip2
# Debian's dpkg
# rpm's rpm, rpm2cpio (Slackware has an 'rpm' package)
# cpio
# infozip's unzip
# cabextract
# mtools' mdir, mtype, mtoolstest
# dvi2tty
# groff
# Perl's pod2text
# pstotext
# ghostscript's gs, ps2ascii
# binutils' nm
# html2text
# lynx
# xpdf's pdftotext
# antiword
# unrtf
# cdrtools' isoinfo
# mp3info

# This will set it up with support for utils that are installed on your
# system.  To include support for everything (if you're planning on
# installing all of those utils later), pass --yes to configure instead of
# --default.  To be prompted for everything individually, just run configure
# by itself.

# To activate lesspipe.sh (if you use bash), run this:
export LESSOPEN="|lesspipe.sh %s"

# To activate it on boot-up from now on, add that line to your /etc/profile
# (It's probably already in there), or create a /etc/profile.d/lesspipe.sh
# with that line in it.
