Terminal blue interface reconfigure

Help
1

i recall i could reconfigure unbound or pihole through terminal. it was blue background. i tried pihole reconfigure but does not work, goes to cmd example screen. trued unbound reconfigure, nothing.

latest v6, not dev. i uninstalled dev and did the bash terminal way install.

The pihole command requires sudo powers with Pi-hole 6:

~$ pihole -r
  [✗] The Pi-hole command requires root privileges, try:
      sudo pihole -r
