"Common" does not mean "the right thing", especially if the output is prone to change - and by definition, everything that has not been declared as giving a stable output can easily change at inconvenient times, depending on moon phase and locale settings. Stable output does not necessarily mean a C API. Tools default to output human-readable prose, and may require specific options to put them into machine-parseable mode. Compare: `date` vs. `date -d +"%F %T"` (parseable). -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
