1 Raspberry Pi is fun, so I thought 10 would be better. While there is a lot of info & videos on physically building a Raspberry Pi cluster, there is almost nothing about software, or RPi to RPi communication.
The situation: RPi-100 -- RPi-109 The problem: How can I run a script from RPi-100 that will execute repeating commands on RPi-101 -- RPi109
"sudo apt-get update'
'sudo apt-get upgrade'
'sudo apt-get install <xxxxx>'
