Almost every Linux CLI tool that requires you to edit a file will consult the `EDITOR` environment variable to spawn the editor you prefer. If you want to use `nano` instead of `vim`, set it as your default editor like this:
`export EDITOR=nano`
Linux tip: Use “ss -tuln” to check for open ports. Filter specific port numbers by adding “| grep :80”, for example.

In many of my projects, I need to run sets of commands both on my workstation during development, and later in a CI/CD pipeline to ship my changes. The solution: Taskfile is a modern take on the classic Makefile, but more capable and less fiddly.
taskfile.dev
If your terminal ever gets confused by random control sequences, for example after you accidentally output binary data, there's a good chance you can restore order with the `reset` command.

The `find` command on Linux is as useful as its argument list is hard to construct.
A refreshing alternative is `fd`. I can just type `fd PATTERN` instead of `find -iname '*PATTERN*`. And holy cow, is it fast!

If you think that mastery requires you to be a “10x engineer” and displaying the most ‘leet of skills, you’re mistaken. Most of mastery is a mastery of the basics.

I can't think of a Linux shell command that I use more often than `ls`. But these days, my `ls` is an alias for `eza`, a modern directory listing command written in Rust for Linux and macOS. It has more features, is faster and more user-friendly.

Tabs vs spaces has always been a controversial topic. Thankfully, #vim isn't biased in any way.
To convert spaces to tabs, use `:set noexpandtab`, then `:retab!`.
Convert tabs to spaces with:
:set expandtab
:set tabstop=4
:set shiftwidth=4
:retab

Did you know that you can literally multiply array elements in #Ruby?
`[1, 2, 3] * 3 # => [1, 2, 3, 1, 2, 3, 1, 2, 3]`
And with a scalar string, it’s a shortcut for `join`:
```
h = { a: 1, b: 2}
h.map { |pair| pair * "=" } * ", " # => "a=1, b=2"
```

I code in the Linux shell with tools that follow the Unix philosophy, "Do one thing, and do it well". One of these tools is `ripgrep`. It's like `grep`, but searches recursively by default, and can filter file types (`-trb` for Ruby).
