Linux trick for debugging scripts: redirecting command output

 Ever wondered how Linux organizes its powerful file system? This visual guide breaks it down perfectly - each directory has its own purpose and logic, making Linux both elegant and efficient. Here’s a quick glance at a few essentials every developer or sysadmin should know: /bin → Essential command binaries /etc → System-wide configuration files /home → User directories /var → Continuously changing data /proc → Interface to kernel data structures It’s fascinating how these directories form the backbone of Linux — once you understand them, navigating and managing the OS becomes second nature. What’s your favorite Linux directory to explore - and why?

Demystifying the Linux Filesystem Ever get lost between /bin, /etc, and /var? This visual map breaks down the core directories, from essential binaries in /bin to user files in /home. A must-know for every developer and sysadmin. Save this post for your next deep dive! Understanding the Linux filesystem hierarchy is fundamental for effective system administration and development work. #Linux #DevOps #SysAdmin #Filesystem #Tech #Programming

I get this question all the time “Where do I start with Linux?” Here’s my honest answer. You don’t study Linux. You live in it. Forget memorizing 100 commands start working like a Linux user. Here’s how 👇 1. Replace your comfort zone. Stop clicking through Windows. Run your next few projects entirely on a Linux VM or WSL. The goal isn’t perfection it’s comfort. 2. Break things intentionally. Delete files. Kill processes. Lock yourself out of sudo. Then fix it. Every panic you feel is how you learn system recovery. 3. Build real habits. • Use grep, awk, sed, and find daily. • Manage permissions. • Write small bash scripts that automate annoying tasks. 4. Understand why, not just how. Don’t just run chmod 755 understand what each digit means. Don’t just restart a service learn what systemd is doing under the hood. 5. Turn repetition into fluency. Open your terminal every day, even for 15 minutes. Linux rewards consistency not memorization. Because here’s the truth: Once you stop using Linux like a stranger and start living in it like home DevOps stops being scary. Linux isn’t just an operating system it’s the language of automation, infrastructure, and control. Learn to speak it fluently. #DevOps #Linux #NimbusCompute #Mentorship #Automation #EngineeringMindset

Do you also scroll through your command history trying to remember how you set something up or to share the steps with your teammates?? Yeah… me too 😅 But I just learned a Linux trick recently that changed everything. You can record your entire terminal session with all thecommands, output and everything without installing anything. Just run “script demo.txt” Then run you commands, debug, install, setup. When you are done, type “exit” Now the whole session is saved in a single text file including the commands and their output. Perfect for debugging, writing documentation, sharing setup steps with teammates. And yes you can replay it later like a movie “scriptreplay demo.txt” Isn’t it awesome ?!

🐧 #2 All About Linux! — "less" command Why “less” is More If you’ve ever used cat to read a huge log file, or struggled with more paging, it’s time to meet your new best friend: less. Here’s why less beats cat, tail, and even more: Scroll freely: Up, down, jump to line numbers, search with / — something cat can’t do. Efficient for large files: Doesn’t load the entire file into memory — huge files? No problem. Dynamic: Works with pipes (grep biglog | less) so you can filter and scroll easily. Tail features: While tail shows the end of a file, less +F gives a live-updating view with scroll-back. 💡 Tip: less is more than a pager — it’s your log inspector, search buddy, and navigation tool all in one. Next time you reach for cat or more, remember: less really is more. 😉 #Linux #SRE #DevOps #CommandLine #LinuxTips #Bash #CLI

💡 Tip for Linux users: Capture all command logs directly in journalctl Ever needed to keep your build or script logs in the system journal for later inspection? You can do it easily using 𝒔𝒚𝒔𝒕𝒆𝒎𝒅-𝒓𝒖𝒏 (no extra tools needed) 𝙨𝙮𝙨𝙩𝙚𝙢𝙙-𝙧𝙪𝙣 --𝙨𝙘𝙤𝙥𝙚 -𝙥 𝙎𝙩𝙖𝙣𝙙𝙖𝙧𝙙𝙊𝙪𝙩𝙥𝙪𝙩=𝙟𝙤𝙪𝙧𝙣𝙖𝙡 -𝙥 𝙎𝙩𝙖𝙣𝙙𝙖𝙧𝙙𝙀𝙧𝙧𝙤𝙧=𝙟𝙤𝙪𝙧𝙣𝙖𝙡 𝙢𝙖𝙠𝙚 𝙗𝙪𝙞𝙡𝙙 ✅ This command runs make build as a temporary systemd service. All output (stdout + stderr) goes straight into the system journal. Then you can check the logs anytime: 𝙟𝙤𝙪𝙧𝙣𝙖𝙡𝙘𝙩𝙡 -𝙪 𝙧𝙪𝙣-*.𝙨𝙘𝙤𝙥𝙚 -𝙣 If you just want to isolate the process under systemd but keep the output in your terminal: 𝘀𝘆𝘀𝘁𝗲𝗺𝗱-𝗿𝘂𝗻 --𝘀𝗰𝗼𝗽𝗲 𝗺𝗮𝗸𝗲 𝗯𝘂𝗶𝗹𝗱 Perfect for debugging, automation, or long-running tasks. No screen/tmux, no extra logging setup — just native systemd power. ⚙️ #Linux #DevOps #systemd #journalctl #automation #sre #sysadmin

Arch install scripts already make the install pretty straightforward, so I never understood why people complain about that part. The thing with Omarchy or any preconfigured setup is that you end up learning someone else's keybinds, tools, and workflow. And when an update changes a bind or adds something new, you either adjust to it or keep unbinding things you don't use. Most people also rely heavily on omarchy-menu (wher is the fun) instead of doing things in the terminal, which kind of defeats the whole purpose of using Arch or linux in the first place. It's not that I dislike #Omarchy it's great but I think people should understand the trade-offs.

Just Learned About Linux Hard Links Did you know that in Linux, you can have multiple filenames pointing to the exact same file data without duplicating a single byte? That’s a hard link! A hard link is essentially another name (directory entry) pointing to the same inode the data structure that represents a file on disk. Unlike symbolic (soft) links, hard links do not create a new file or store a path to another file. they simply add another reference to the same underlying data. - All hard links to a file share the same inode number. - They are indistinguishable from the original file there’s no concept of “original” vs. “link.” - The file data persists as long as at least one hard link exists. - You cannot create hard links to directories (on most modern Linux file systems like ext4) to prevent circular references and filesystem corruption. - Hard links must reside on the same filesystem as the original file, because inodes are filesystem specific. But be careful: some editors (like nano) break hard links by creating new files #Linux #Unix #DevOps #SystemAdministration #CommandLine #Programming #TechTips #LearnInPublic

Over the past few weeks, I explored different ways to monitor Linux logs live while debugging deployments and services. Here’s what I learned: 1. tail -f : quick and simple, perfect for single log files 2. tail -F : useful when you want to monitor rotating logs 3. less +F : great when you want to pause, scroll and search inside the log 4. multitail : when you want to see multiple logs at once Each tool shines in a different situation. Knowing when to use which one saves huge time. I’ve written a blog post that dives deeper into each use case with practical examples.
