Could anyone help me blank the local terminal on bootup? I need the screen completely blank before a fullscreen app opens. I've removed everything but I still have -

pi@raspberryPi:~$

I can manually remove it using

sudo sh -c "TERM=linux setterm -foreground black -clear all >/dev/tty0"

but putting this in sudo crontab -e, a systemctl script, or /etc/rc.local isn't working.

The service works if I run it manually, sudo systemctl start black.service so I think it's just a timing issue, can I make it wait for the user to logon?

  • If I recall, that prompt can be modified via an environment variable. PS1? So export PS1=''

  • not sure where I'd put that? I tried it in terminal and nothing happened, whereas the command above works if typed in manually Nov 29, 2023 at 12:17
  • I've got it work in a hacky way, but not the most elegant. Ideally would like a nicer soloution. I've added /bin/sleep 0.1 before the commands in the sh file and just repeated all it about 50 times. Nov 29, 2023 at 12:36
  • You can try putting it in ~/.bashrc

The pi@raspberryPi:~$ is created in .bashrc which is called by the .profile file. Those two file can be changed to to do something else.
