Working on Fedora Silverblue introduced me to toolbx and distrobox, two great ways to build isolated shell environments in containers. You can install what you need, and if things go sideways, you can simply rebuild them. Their integration into the host system is seamless, it's amazing.

I highly recommend giving them a try:

- https://distrobox.privatedns.org

The `find` command on Linux is one I use the most. If only it was easier to construct its argument list! I hate those single-dash-but-long-word options.

A refreshing alternative is `fd` because it has more sensible defaults. For example, I can just type `fd PATTERN` instead of `find -iname '*PATTERN*` to search for files that match a keyword somewhere in their names, regardless of capitalization. And boy, is it fast.

The introduction of the /proc filesystem was a genius idea that gave system administrators direct control of the running Linux kernel. In his article "How to tune the Linux kernel with the /proc filesystem", David Both, author of the books I use as study material for my Linux Master Course, explains how to change kernel parameters at runtime.

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`. Like the venerable `grep`, it filters lines from files that match a specific keyword or pattern. But it searches recursively by default, and can easily filter file types (e.g. `-trb` for Ruby code).

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 `exa`, a modern directory listing command written in Rust for Linux and macOS. It has more features, and is faster and more user-friendly.

Did this ever happen to you? You edit a system configuration file, only to get an error message from vim because you forgot to open the file as root.

Good news: You can finish your change after all. Simply enter the following vim command:

`:w !sudo tee %`

If you're interested in how this works in detail, let me know!

Attending #ShipItCon in Dublin today. It’s nice to have a conference reachable just by public transport for a change. And I’m really enjoying the talk by Laura Nolan about how teams and their automations interact.

Not only can you use `tail -f <file>` to continuously output a file (a service log, for example) while it's being written, you can even filter specific keywords in the process:

`tail -f <file> | grep <keyword>`
