when to create a new terminal when executing commands
Hello! I’m a super-beginner (just started doing the tutorials yesterday ). I’ve done the all the understanding ones, creating a workspace one, creating a package one, and writing a publisher / subscriber in Python. In these tutorials, we are told to execute commands, sometimes in a new terminal and sometimes in the same terminal. My question is, when do we need to execute commands in a new terminal ? When is it okay to execute commands in the same terminal ?
I am running humble on Ubuntu 22.04
For me the big rule is "Does this think need to stay running while I do other things?" For example If I'm running my publisher node in one terminal, and want to see the data it's publishing, I need to start my node in one terminal, and in another (since I need to keep my node running) I can run
