+- General notes:
+    - Subcommands may be shortened (e.g. as `ip a` instead of `ip address`)
+    - For subcommands like `address` and `link`, it will default to show all elements if no further option is specified.
+- General options:
+    - Specified before the subcommand (e.g. `ip -c a`).
+    - `-c`: Show colored output.
+    - `-4` or `-6`: Show IPv4 or IPv6 addresses only.
+    - `-s`: Show stats (bytes, packets, errors, dropped, etc. for RX and TX).
+    - `-br`: Show brief with one line per interface (MAC address and status for `link`, addresses for `address`).
+    - `-o`: Show one line per interface (but all info unlike `-br`).
+    - `-j [-p]`: Print as JSON. Add `-p` for pretty printing.
+- Show L2/MAC addresses:
