xsos --ipv6 doesn't produce expected content

[SenseiC]

Cloned the latest code just to make sure not caused by outdated source code:

$ xsos -h | grep -E 'Version|ipv6'
 -6, --ipv6         parse ip addr output for IPv6 addresses instead of IPv4
Version info: xsos v0.7.28 last mod 2022-01-21

So the help implies that passing -6 or --ipv6 will generate output for IPv6 addresses as opposed to v4, but instead you get nothing of the sort. Consider the following (I scrubbed the content because it has come from a customer's server):

$ xsos --scrub --ip .

I suspect it has to do with this "sed" error at the bottom. I avoided trying to insert this second output as "code" because it contains grave accents and that seems to mess up the post's formatting.

Sidebar - I've always wondered why the --ipv6 | -6 options exist since the --ip | -i option outputs the IPv6 information already. I had expected the --ipv6 | -6 options to, in effect, toggle the --ip | -i options' output to display IPv6 addresses instead of IPv4.

On a related note (I believe)... something else definitely amiss with the IPv6 output...

Looking at sos_commands/networking/ip_-d_address from my SOS Report I see:

$ grep virbr0 -A99 sos_commands/networking/ip_-d_address

Note this has no IPv6 address, i.e. this expression at line 2530 should return false:

2529        # If $i has an ipv6 address, time to figure out what it is
2530        if grep -q "inet6" <<<"${iface_input[$i]}"; then

Neither virbr0 and virbr0-nic have inet6 text:

$ grep virbr0 -A99 sos_commands/networking/ip_-d_address | grep inet6 -c
0

and yet they both appear in the IPv6 output...

$ xsos -i --scrub .
