# To use this filter with less, define LESSOPEN:
# export LESSOPEN=&quot;|/usr/bin/lesspipe.sh %s&quot;
#
# The script should return zero if the output was valid and non-zero
# otherwise, so less could detect even a valid empty output
# (for example while uncompressing gzipped empty file).
# For backward-compatibility, this is not required by default. To turn
# this functionality there should be another vertical bar (|) straight
# after the first one in the LESSOPEN environment variable:
# export LESSOPEN=&quot;||/usr/bin/lesspipe.sh %s&quot;
