One essential command to know when you are experimenting in Linux is the command to see which processes are running in your machine, just in case you need to kill one of them for any reason. This command is top and you use it like this:
- Type top in a Linux Terminal and press Enter:
pi@raspberrypi:~ $ top
- You should see something like this:
- To quit this command just press Ctrl+C
Hope it helps.
