# To use this filter with less, define LESSOPEN:

# export LESSOPEN="|/usr/bin/lesspipe.sh %s"

# 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="||/usr/bin/lesspipe.sh %s"
