Microsoft has delivered a suite of native Linux-style command-line tools for Windows, and now the cat, cp, and ls commands you normally use in a Linux terminal can run as actual Windows commands instead of being hidden inside a virtual machine. · Published June 2, 2026 · Updated June 3, 2026 · ⏱ 5 min […]

The point where grep really shines is when you are staring at a log file with 40,000 entries and only one error buried somewhere in the middle, and you desperately need to see it on your screen right now. I once dealt with intermittent 500 errors on a production server. I spent hours manually scanning […]

If you've ever loaded a 40,000-line log file into your terminal and watched it choke while trying to display the entire file all at once, then the less command in Linux is something you'll want to use. less loads only enough of the file to fit on your screen, waits until you're ready, and allows […]

You wrote a Bash function that returned the value you were trying to see. Then, you started searching through variables, only to find that none of them contained anything. This can happen to anyone. The problem is not with your function (it works exactly as designed) or with Bash itself (it behaves the way it […]

Rust 1.96.0 shipped on May 28, 2026, and solves one of the language's longest-standing ergonomics issues. The problem involved range types that could not implement Copy. This limitation frustrated many library authors over the years, and Rust 1.96.0 resolves it through the implementation of RFC 3550. Additionally, the release stabilizes two new assertion macros and […]

You are sitting down to write a 300-line deployment script and realize the same 15 lines of disk-space checking code appear in four different places. If you make a change in one location, you now have to go hunting through your entire codebase to see where else those lines of code exist. And if you […]

The same three Linux kernel privilege escalation flaws, all discovered using AI-assisted auditing tools, appeared within weeks of one another between late April and early May 2026. During that same period, Linux stable kernel maintainer Greg Kroah-Hartman made a strong argument in favor of Rust at the Rust Week 2026 conference held in Utrecht, Netherlands. […]

I am knee-deep in a production project. I want my script to take 200+ server log files from a directory, read each one individually, and never require me to touch the keyboard while it runs. At that point, Bash loops stop being about tutorials and start becoming practical. I have been there too. My first […]

Fedora 44 arrived with GNOME 50 preinstalled. Automatic NTsync support was also built in, making Windows gaming compatibility smoother out of the box. The Nix package manager is now officially available in the Fedora repositories as well. In real-world usage, from AI developers running coding agents to computer science students working with Django and Docker, […]

The rm command in Linux does not have an undo option. Once you type the wrong path with rm -rf, you will realize it immediately when your files are gone, not because of an error message, but because everything simply disappears. I once watched a junior system administrator delete an entire /var/www directory on a […]

You create an executable script that continually retries a failed network or database connection, but it only runs once and exits. In other cases, the condition logic is reversed, causing the loop to continue indefinitely. If either situation sounds familiar, you are in the right place. I once wrote a backup script for a production […]

California's new law regarding online service providers has attracted much interest among the Linux community. After open source developer and privacy advocate opposition to an original proposed bill, CA State Legislature is proposing a bill (AB 1856) to amend its Digital Age Assurance Act which would potentially exempt all open-source operating system platforms from age […]

Your cron job ran at 2 AM, but the server was rebooted at 1:59 AM for a kernel update. Nothing ran. No alert. No log. You find out three days later when a backup directory is suspiciously empty. If that sounds familiar, you've already met the exact problem systemd timers solve. I've watched this exact […]

The decision to use a bash for loop comes down to how much time you want to spend typing file names. If you've ever found yourself with 200 files all needing the same operation run on them, as I did during a log cleanup task, then using a for loop will save you hours of […]

The mv command in Linux may surprise you at how difficult naming a file can be, especially if you find yourself executing mv config.yml config.yml.bak in the wrong server environment only to see your necessary configuration (the one in the destination) disappear without any type of warning or prompting. This same error happened to a […]

The anacron command in Linux can catch "silent failures" such as the one described above. A user had a cron job running nightly with no issues for about 3 months. The server received a kernel update which caused the server to restart late in the week (Thursday) but none of the other admins knew that […]
