cat<<USAGE
Usage: ${0##*/} <version-1> <comparison> <version-2>
Compare two version numbers. The <comparison> argument can be one of; eq
(equal-to), lt (less-than), gt (greater-than), le (less-than-or-equal-to), or
ge (greater-than-or-equal-to). Returns a successful exit code if true.
Examples:
foamVersionCompare 5.4.3 gt 5.5.1
foamVersionCompare 5.4.3 gt 5.5.1 && echo True || echo False
if foamVersionCompare 5.4.3 gt 5.5.1
then
echo "5.4.3 IS greater than 5.5.1"
else
echo "5.4.3 is NOT greater than 5.5.1"
fi
