I'm constantly dealing with IPv4 addresses (millions)=2E Sorting the mass is never perfect, and I'm forced to *visually* fix those out of order=2E Yet I continue to (later) find some I've missed -- I'm sick of it! Thus far, I've found I attain the best results with sort(1): sort -t =2E -k 4,4n -k 3,3n -k 2,2n =2E/TCPLIST | sort -g>=2E/SORTED Which ends up pretty damn close=2E But not perfect=2E :( Then it occurred to me that adding INET_ATON to sort, allowing for an additional -inet option to sort(1) for IP addresses -- hell if MySQL can provide it[1], why the heck can't sort(1)? Else I guess I'll have to try and give a shot at cobbling up a C utility to manage it=2E But seems like too much work for something that'll only accomplish one thing=2E :( Thanks for any thoughts, or further insight=2E [1] https://dev=2Emysql=2Ecom/doc/refman/5=2E7/en/miscellaneous-functions=2Ehtml#fu= nction_inet-aton --Chris
