Eliminar elementos de la barra de menús a través de la línea de comandos

Encontré una posible respuesta en superusuario.com :

#!/bin/sh

# Removes the Wifi menu from the menubar.
# This setting is set on a per-user basis, so needs to be run as the user
# Will require a logout. A 'kill SystemUIServer' might work?

OIFS="$IFS"

menutemp=$(defaults read com.apple.systemuiserver menuExtras)
menutemp2=$(echo $menutemp | sed 's/( //')
menutemp3=$(echo $menutemp2 | sed 's/ )//')

IFS=','
read -a menuitems <<< "$menutemp3"
IFS="$OIFS"

for (( i = 0 ; i < ${#menuitems[@]} ; i++ ))
do
    if [ "${menuitems[$i]}" = '"/System/Library/CoreServices/Menu Extras/AirPort.menu"' ]
    then
        /usr/libexec/PlistBuddy -c "Delete :menuExtras:$i" ~/Library/Preferences/com.apple.systemuiserver.plist
    fi
done

Lo probaré y actualizaré.
