Configurating LCD display

[guilherme-vieira]

Hi, recently I got a LCD 3,5 inch tft display. I search the web and found out that I need to use few commands as sudo REPO_URI=https://github.com/notro/rpi-firmware rpi-update but whenever I try to use commands like this I get the error message: -sh:sudo: not found Is there any way so I could use this kind of command to install the drivers for my lcd? Thank you.

retry the command, but do not use sudo because you are already logged in as root
