What are the top 3 or so Linux do's (or don'ts) you've learned over the years?

Besides of course rm -rf / :laughing: What are other huge must-do’s or mistakes that every new Linux user should avoid?

@rossj I’ll follow up and edit my answer here shortly.

  1. Don’t stick to one distro. - Often if you fall in love with Linux you can become comfortable with the first distro you try and miss out on distros that may suit you even more. Also see:
  1. Enable unattended security updates. - We may not need antivirus software. But cybersecurity threats for vulnerable software and packages continue to increase so you should always stay up to date. On Ubuntu-based distros it looks like this:

  1. Setup RAID NVMe’s on your laptop/workstation. - One of the biggest performance gains you can have is installing SSD and especially NVMe storage on your system. Of course, this goes for any OS. But if you really want your system to fly!! - use 2x the NVMe drives in RAID 0 for example. Which is as simple as:

Backup config files…always backup config files!

Agreed! I lost ssh to my VPS and had no way to recover. It was a pain to reconfigure everything. I now backup to git.

One of my first mistakes(before actually knowing to much) was to install Arch(yep,not ubuntu,not linux mint) as my first distro… learn by doing right? :stuck_out_tongue:

By accident wiping the wrong disc(with all my important files…haha) and then…didn’t actually enjoy it without a DE(didn’t quite understand why mine didnt look at all like all cool custumized pictures online):rofl::rofl:

So yeah: Set your goals,but DON’T go from windows to full terminal install unless you have the time and knowledge😁 and keep an eye on what you wipe and format when building your partitions and system up!

Now i run most of the distros,and yeah! Now i know a bit more than those days👍

Top 3 Do’s:

  • Install a distro for your NEED and usage(but feel free to test out different distros)

  • Read instructions and guides if available and take your time to know the distro of choice and “common” errors/mistakes so you save time and enjoy it the way you should

*Update and backup your data


Dont’s:

*Do NOT install a distro you will not handle(skill wise or operational in the os)

  • Install extra tools and “glitter” that you have not researched or read up on beforehand aka a new DE incompatible with your current DE without knowing how to correct it etc

*Dont run commands in the terminal without knowing what can happen.


Extra(own experience):

IF going the Ethical hacker route:
You can still do most of your tasks with a combination of windows AND regular linux(with extras added as you go)

you do NOT need blackarch(it’s cool…sure)
I can mostly name 10-15 tools of choice depends on the task at hand ofc,but surely without needing them ALL in a "hacking distro":rofl:

This was a long one…but i like writing…hehe

Have a great one!

My number one do is to install cockpit. It’s super nice to view system resources and terminal via web interface.
