I'm about a decade removed from having ANYTHING to do with Linux, and being in the console, and at my age, the memory isn't helping matters.
I used to admin a CSS (gaming) server, but it was based on a CentOS install. I remember having to install SUDO, and Nano, etc., but I barely remember all the commands, and until I have access to my old notes, I've been trying to watch YT clips, as well as Goog-Fu my way through jarring the cobwebs loose.
I've had a few things I've noticed, and was hoping I could ask some of the more established Linux folks for a hand..
I know (been a lurker until now) that these are based on OpenWRT (new to me) thanks to posts here, *but*, I've also seen Debian referenced *somewhere* while I was exploring around in the console (SSH).
Do I look for Debian install pkgs then?
Or any particular distro's recommended?
Does apt-get apply still? Or is it another command in this OS?
Should I install SUDO first? Or is there something more pressing?
Second, what would the command be to change the following 'code'? (Pardon me for not remembering the proper term for the group user thingy referenced in the Pic.)
The 4 (in user acct: Dockem) is thanks to the 'allusers' account screwing with other (otherwise unrelated) accounts permissions settings. That 4 needs to be a 12 to be in the proper user account (group, whatever it is I'm forgetting at the moment lol).
