I didn’t get to spend as much time tinkering and learning this week, but I still learned some new things!
- Wireguard is great! I had been using OpenVPN because when I initially set up my machine, my VPN had a bug with Wireguard. I was setting up a raspberry pi today for some more tinkering, and I decided to try Wireguard to see if the bug was fixed. Not only is it fixed, but Wireguard is much easier to work with. Not hating on OpenVPN, but I’ll definitely be preferring Wireguard going forward.
- Proper use of
find, particularly with regex. This is ongoing. I’ve been using find for awhile, but not with full understanding of it’s options and syntax. I’m starting to get a better understanding of how to use it to find and manipulate the files I’m looking for. One of the biggest things that’s tripping me up withfindand regex is designating the path. - How to set up a new user. This was interesting. I already knew the basics,
adduser -m username,sudo passwd username, but what I didn’t know anything about was--skelfor copying over the skeleton shell config files. I didn’t even know the skeleton config files existed. - The shell prompt can be customized. This was interesting. I was setting up a non root user on a vps that I have, and after creating the user, all I had was the
prompt. Nouser@host, and no working directory. After some reading I found that addingPS1='$(whoami)@$(hostname):$(pwd)$ 'to ~/.profile will show a more traditionaluser@host:working/directory$prompt. I’m sure this is not the only way to do this, and may not be the best way to do it, but based on my limited knowledge, it is the way that I’m currently doing it on my vps.
As someone also starting to get into Linux I appreciate these posts
I’m glad they’re useful for you!
check fd-find, “A simple, fast and user-friendly alternative to ‘find’”. Really good trust me
I will look into that. Thank you!
If you code adding the current branch to your shell prompt will change your world.
Also, if you are getting good use out of find, you should learn to pipe the output to GNU parallel. Put those cores to work!
Depending on your distribution it may also just be called fd in the package manager
Check out using something like oh-my-zsh if you want a deeply configurable shell experience that isn’t super far off the stock bash path.
I kinda like fish tbh. The dracula theme is much better and more features than stock zsh
There’s also oh-my-fish.
Fish + starship is a killer combo.
There’s also oh-my-posh, which was originally a powershell prompt, but it was rewritten as a go application that works on (I think all) mainstream shells.
I’ve heard of oh-my-zsh, but I haven’t wanted to deviate off of bash until I have a good grasp on bash first.
The project aims to make Bash vs Zsh as similar as possible. There is little difference except for customization. Switching to Fish or Spaceship will jump that barrier.
My advice: make your home directory a git directory. You can ignore everything in a gitignore, then make exceptions, like your vim configs, shell configay and so on. You have version control and on a new host you can just git clone and bam, you have your usual setup.
Or simply create a dotfiles repo and symlink configs.
Yes, this. Don’t put your whole home directory in git.
I’ve never used git to publish/make myself a repo before. That’s something I’ve been meaning to learn but haven’t quite gotten there yet. However, with the amount of tinkering, and breaking I’ve been doing, I think I’ll move it up on my priority list.
I’ve also got shell scripts I’ve been writing and tinkering with and having proper version control (versus script, script.copy, script.copy.bak…) would also be nice.
It’s not actually hard if you know some high level basics. I recommend to use a git GUI or tui, makes things even easier. I personally use lazygit.

Ohhh. Thank you. I will give that a read through!
re 1: out of curiosity, do you encounter dnsleaks when using wireguard?
re 4: you can also check out https://starship.rs/, which helps configure shell prompt very intuitively with a toml file.
DNS leaks don’t depend on what VPN protocol you use. They only depend on how you configure your DNS resolver and routing.
I didn’t k ow there were dms leak issues. I will investigate. If I’m finding that I’ll likely switch back to openvpn
Regex is not the most oftenly used feature of
find. Have you already learned how to use-exec,-delete,-print0together withxargs?That’s what I’m finding. I’m not certain I need regex for what I want to accomplish with find. I’m reorganizing my media libraries, and I have a mix of mp4 and mkv files. I want to be able to find all mkv and mp4 files and move them using regex like
'.+\.(mp4|mkv)'I have learned how to use find with
-execand-delete, but I haven’t gotten to-print0orxargsyet.You don’t need a regex for that, you can write
\( -name '*.mp4' -o -name '*.mkv' \).Thank you! That worked perfectly. I had to do some digging through the man page to find that
-oflag!
I really need to learn find.
How is the rust replacement?
How is the rust replacement?
fd > find. It’s a lot faster, and I find the syntax to be better.
