Somewhere above I mentioned that the default for .words was $_. Not $I,
which you have chosen to use. So you'll need to specify the explicit
invocant:
ip -o -f inet addr show | perl6 -e 'for lines() -> $I { if ( $I ~~
/enp/ ) { say "Interface <" ~ $I.words[0] ~ ">\nIP<" ~ $I.words[3] ~ ">"; }
}'
If I swap out your match for a prefix that exists on my system:
pyanfar Z$ ip -o -f inet addr show | perl6 -e 'for lines() -> $I { if (
$I ~~ /wlan/ ) { say "Interface <" ~ $I.words[1] ~ ">\nIP<" ~
$I.words[3].split("/")[0] ~ ">"; } }'
Interface <wlan0>
IP<10.8.201.162>
(For this one, I also removed the CIDR mask from the end.)
