Hope this is the correct forum.
I'm new to Raspberry Pi and programming.
I have been trying to get my script running at startup without any success, until I found an answer on stack overflow.
I wrote the code into
/etc/rc.local which got the script to run at startup. The script keep on running. I have had the SD card into my PC where i added
init=/bin/sh, to cmdline.txt which gives me an command line when starting up my Raspberry. When I write
sudo nano /etc/rc.local I can open the file, delete the code from earlier, but I can't save the file.
Any good advice on how to fix this problem so my script ain't running at boot-up in my terminal anymore?
