Man pages are awesome! To find the “Manual” for anything in Linux, just open a terminal and type man with the subject you are looking for. ie:
What if it’s something less precise? Use the -k switch to get a list of anything containing the subject you are looking for. ie:
man -k network
Once you’ve read what you need, just hit q to quit back to the terminal.
