Usage: wgctl shell
Start an interactive wgctl shell. Supports all wgctl commands
directly (no 'wgctl' prefix needed), plus any bash command.
Builtins handled: cd, export, unset, source
Everything else: passed to bash
Examples:
wgctl shell
wgctl> list
wgctl> inspect --name phone-nuno
wgctl> ls /etc/wireguard
wgctl> exit
