Walkthrough

The show() function in the rc.library.source script is modified to remove peer address patterns from its output pipeline when processing two arguments, adding an additional sed substitution before whitespace trimming.

Changes

Cohort / File(s)	Summary
Output Cleaning Enhancement etc/rc.d/rc.library.source	Modified the show() function to include an extra sed substitution that removes peer addresses (matching peer x.x.x.x/x) alongside existing metric cleanup, with leading space trimming applied afterward.

Poem

🐰 Tidy whiskers, tidy code,
Peer addresses hit the road!
With sed's precision, swift and keen,
The cleanest output ever seen.
Leading spaces trimmed just right.

In `@etc/rc.d/rc.library.source`:
- Line 60: The sed token that strips " peer ..." currently only matches IPv4 and
uses unescaped dots; update the sed fragment in the pipeline that contains "s/
peer ...//g" so it accepts either an IPv4 dotted-quad (with dots escaped) or an
IPv6 address (hex digits and colons) followed by "/<prefix>" — use the existing
extended regex mode (sed -r) and an alternation grouping to match either address
form before the "/[0-9]+" prefix length, and keep the rest of the pipeline (the
ip -br addr show ... | awk ... | sed ...) unchanged.
