# lesspipe.sh, a preprocessor for less (version 1.83)
#===============================================================================
### THIS FILE IS GENERATED FROM lesspipe.sh.in, PLEASE GET THE ZIP FILE
### from https://github.com/wofr06/lesspipe.sh/archive/lesspipe.zip
### AND RUN configure TO GENERATE A lesspipe.sh THAT WORKS IN YOUR ENVIRONMENT
#===============================================================================
#
# Usage: lesspipe.sh is called when the environment variable LESSOPEN is set:
# LESSOPEN="|lesspipe.sh %s"; export LESSOPEN (sh like shells)
# setenv LESSOPEN "|lesspipe.sh %s" (csh, tcsh)
# Use the fully qualified path if lesspipe.sh is not in the search path
# View files in multifile archives:
# less archive_file:contained_file
# This can be used to extract ASCII files from a multifile archive:
# less archive_file:contained_file>extracted_file
# As less is not good for extracting raw data use instead:
# lesspipe.sh archive_file:contained_file>extracted_file
# Even a file in a multifile archive that itself is contained in yet
# another archive can be viewed this way:
# less super_archive:archive_file:contained_file
# Display the last file in the file1:..:fileN chain in raw format:
# Suppress input filtering: less file1:..:fileN: (append a colon)
# Suppress decompression: less file1:..:fileN:: (append 2 colons)
#
# Required programs and supported formats: see the separate file README
# License: GPL (see file LICENSE)
# History: see the separate file ChangeLog
