    I am stuck at step 9. The first thing I did was this:create a filefrom os import syssys("raspivid -o.........demux=h264")sudo crontab -e Then I would type in this:raspivid -o ............. demux=h264But I am not sure about that because the tutorial said thisAnd then we will enter the command that adds that file to auto-strartup in the cron manager.I do not know what "that" file is. maybe the upon_startup.sh? And what exectlyWe will call the file pibot.sh which will give commands to start all kinds of python scripts to operate the robot. Let's go over it: (We sudo with curtain Python programs to allow the program to access the GPIO)raspivid -o - -t 0 -hf -w 640 -h 360 -fps 25 | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554}' :demux=h264The code that does...see more »I am stuck at step 9.

It is a simple shell script that runs everything

    What does the "755" after chmod do. I know the 7 stands for: read, write, execute and the 5 for: read, execute. But why do you need three of those numbers and not 1?
