Can anyone suggest a nice unix pipeline filter using lightweight tools
(no python) to output an ipv6 address in reduced format. That is, with
the extra zeros removed and colons condensed according the normal ipv6
rules. Bonus for an example that leaves timestamps unscathed. In my
case, the ipv6 address is inside square brackets. For example:
ipv6 Thu Nov 16 00:05:34 PST 2017 [2603:01c2:1800:a8c0:0000:0000:0000:0001] foo bar baz
should become:
ipv6 Thu Nov 16 00:05:34 PST 2017 [2603:1c2:1800:a8c0::1] foo bar baz
