Linux Self-Assessment and Progress Tracking

Stop manually setting up VMs! In this video, I dive into NixOS, the Linux distro that lets you code your entire OS.  #NixOS #Linux #DevOps #Homelab #Automation #SysAdmin #Proxmox

Linux eBPF Syscall Tracer Snoop Now Available for High-Performance Monitoring 📌 snoop is a blazing-fast Linux syscall tracer built on eBPF, letting apps run unimpeded while tracing-no more process interruptions. It decodes 60+ syscalls, decrypts TLS traffic, and works in containers with zero overhead. Built in Rust and optimized for async performance, it’s the next-gen observability tool for DevOps and developers who demand speed without sacrificing insight. 🔗 Read more: https://lnkd.in/dzV9vitS #Ebpf #Linux #Syscalltracer #Snoop #Tracepoints

cron is a background program that runs on almost every Linux server. Its task is to start commands or scripts at fixed times, for example, every day at 3:00 am or every Sunday at 11:00 pm. This blog covers syntax, customization, and even alternatives like systemd-timer. #Linux #Automation #DevOps #RheinwerkComputing #RheinwerkComputingBlog Read more. https://hubs.la/Q04cTyv40

🛠️ Linux Troubleshooting Mindset (Beyond Basics) While working on Linux systems, I realized that real learning starts when things break. Instead of just running commands, I focused on understanding why issues happen and how to debug them. 📌 My approach: - Check service status (systemctl) - Verify open ports (ss / netstat) - Test locally (curl / ping) - Analyze logs (journalctl) 💡 Key Insight: Linux is not about memorizing commands—it’s about logical troubleshooting and understanding system behavior. #Linux #DevOps #SysAdmin #Troubleshooting #LearningByDoing

Rename a directory in Linux using the mv command. Key points: • mv is used for both moving and renaming • renaming = moving to a new name in the same location • supports relative and absolute paths Examples: • mv old_directory new_directory • mv /path/old /path/new • use quotes for spaces Tips: • use -i to prevent overwrite • use -v for verbose output Full guide 👉 https://lnkd.in/dVtVTuP8 #Linux #DevOps #SysAdmin #VSYSHost #CLI #Infrastructure

It is interesting how often people overlook the basics in tech. In Linux, simple commands are not just beginner tools. They shape how people navigate systems, troubleshoot issues, and build real technical confidence. For people already working in IT, support, or engineering: What is one Linux command you think every beginner should understand early, and why? It would be interesting to see which command comes up most. #Linux #ITSupport #SysAdmin #TechLearning #Technology

Some Linux commands don’t look powerful… until you actually start using them These feel like small tricks, but they can seriously improve your workflow : 🔹 watch -n 2 df -h → Runs a command every 2 seconds (live monitoring) 🔹 alias cls='clear' → Creates your own custom shortcut command 🔹 !! → Repeats the last executed command 🔹 tac logfile → Displays file content in reverse order 🔹 yes "test" → Repeats a string continuously Not every useful command is complicated… sometimes the smallest ones feel like magic when you discover them #Linux #LinuxCommands #DevOps #SystemAdmin #Productivity

If you use Linux daily… these are the commands you probably type without even thinking Simple? Yes But these are the ones that make your workflow smooth 🔹 ls -ltr → Lists files in reverse time order (latest at bottom) 🔹 clear → Clears the terminal screen 🔹 history → Shows previously used commands 🔹 echo "text" → Prints text or variables in terminal 🔹 man <command> → Opens manual/help page for any command Sometimes it’s not the complex commands… but the small ones you use every day that actually matter #Linux #LinuxCommands #DevOps #SystemAdmin #Learning

𝐋𝐢𝐧𝐮𝐱 𝐟𝐢𝐥𝐞 𝐩𝐞𝐫𝐦𝐢𝐬𝐬𝐢𝐨𝐧𝐬.... I attended an informative session run by Yacquub Adan earlier today about Linux file permissions and here are some of the points Every file or directory in Linux is tied to three types of owners: 📌 Owner – the user who created the file 📌 Group – a set of users who share the same access permissions 📌 Others – everyone else who isn’t the owner or part of the group There are three basic permissions you can assign: 1️⃣ Read (r) – allows viewing the contents of a file 2️⃣ Write (w) – allows modifying the file 3️⃣ Execute (x) – allows running the file as a program Credit ByteByteGo #linux #devops #tech
