I'm fairly new to Linux, but wanted to ask this question about how people find their way around new commands.
For example, I recently had an issue with a webpage that wouldn't connect to a service that I was running on an Ubuntu server.
I googled the firewall setup for Ubuntu, found a command to open certain ports, copied/pasted with the changes I needed and had everything working.
My question is, what's the "pro" way to do this. I'm guessing that pros would find the firewall in the command line, run a command like "man" to find the manual, piece together the command line arguments and run everything they need.
Is there a pro way to find your way around Linux without resorting to Google everytime? I feel like such a fraud when I'm using Linux!
