Linux Untar Command Like a Pro

🐧 If you're new to Linux, save this! These 10 basic commands are all you need to get started: ✅ pwd – Find your current directory ✅ cd – Navigate through files & folders ✅ ls – View contents of a directory ✅ cat – Create a new file ✅ cp – Copy files to another directory ✅ mv – Move files ✅ mkdir – Create a new directory ✅ rmdir – Delete directories ✅ locate – Find any file quickly ✅ sudo – Run tasks with admin permissions ✅ head – View the first lines of a text file The terminal feels overwhelming at first — but it all starts with these. 💻 #Linux #TechTips #Programming #OpenSource #Coding #Developer #LearnToCode

📂 Understanding Absolute vs Relative Paths in Linux Navigating the Linux file system becomes much easier once you clearly understand the difference between absolute and relative paths. 🔹 Absolute Path Starts from the root (/) and gives the complete location of a file or directory. Example: /folder1/folder2/folder3 ✔ Works from anywhere in the system 🔹 Relative Path Defined based on your current directory. Uses: . → current directory .. → parent directory Example: From /folder1/folder2/folder3 → cd ../../f1/f2/f3 💡 Key Takeaway Absolute path = full address Relative path = directions from where you are ✅ When to Use What? Use absolute paths when you need reliability (scripts, cron jobs) Use relative paths for quick navigation and portability within projects Mastering both helps you move efficiently, write better scripts, and manage files like a pro in Linux 🚀 #Linux #DevOps #Programming #SystemAdministration #Learning

Completed OverTheWire Bandit Levels 0-11 as part of my Linux learning. 🎉 Instead of just solving each level, I documented the process - what I tried, what failed, and what I learned. A few standout concepts: • File navigation quirks (like handling files named -) • Using find with ownership and size filters • Understanding how sort | uniq actually behaves • Extracting hidden strings using strings and grep • Decoding base64 and ROT13 data streams Each level introduced a small but important Linux concept that builds real familiarity with the command line. All solutions documented on GitHub: https://lnkd.in/exZzNphJ Linux stops being intimidating once you start interacting with it directly. CoderCo #Linux #DevOps #OverTheWire #Bandit #LearningInPublic

One thing that really clicked for me when learning system programming on Linux: std::thread is not “magic”. Under the hood, it often relies on native OS threads — and on Linux, that typically means pthread. So the abstraction looks like this: C++ code → std::thread → pthread → OS threads That changed how I see modern C++. std::thread is not replacing low-level threading — it is giving you a safer, portable interface on top of it. And that is why: you get RAII type safety and cleaner APIs without losing performance. The real takeaway : When you use std::thread, you are still using system threads — just with a better interface. Curious: Did you start with pthread or directly with std::thread? #cpp #cplusplus #multithreading #concurrency #linux #softwareengineering #programming

Boost your productivity in Linux with wildcard characters. This guide covers how *, ?, and [] enable efficient pattern matching, helping you search and manage files with precision—an essential concept for developers, system administrators, and IT professionals. 👉 Read more: https://lnkd.in/dDsKSSEB #Linux #DevOps #SystemAdministration #Programming #ITProfessionals #TechSkills #CommandLine #Automation

Finally, a small step forward… 🚀 I’ve successfully packaged and uploaded my compiled code. You can explore it here: https://lnkd.in/gkA4sA3g Feel free to decompile it, analyze the structure, and experiment with your own edits. Always learning, always building. 💻 #Learning #Development #Linux #CommunityDeveloper #Space

Learning Linux streams and redirection Commands and operators used: echo, cat, ls, >, >>, 2>, &>, <, /dev/null, () What’s happening here: Created files and wrote text using echo with > Read file contents using cat and input redirection < Appended data to files using >> Triggered an error with ls fakefile and redirected it using 2> Combined standard output and errors into one file using &> Suppressed errors completely by redirecting to /dev/null Used () to group commands and handle outputs together Hands-on practice with controlling input, output, and error streams in the terminal. #Linux #CommandLine #DevSkills #LearningJourney #Tech #coderco

This week, I started learning Linux Instead of just running commands, I focused on understanding what’s happening underneath. Day 1 — Fundamentals - Learned Linux architecture and how components interact - Understood the role of systemd Day 2 — Command Practice - Built my own cheat sheet of commonly used commands for reference - Focused on file handling, navigation, and system interaction Day 3 — Processes, Services & Logs - Explored process management (`ps`, `top`, `kill`) - Worked with services using systemctl - Checked logs to understand system behavior (journelctl) - Traced how a service runs on my system step by step --- What I learned : - Everything in Linux is either a file or a directory - Everything starts with a process  --- Next, I’ll be going deeper into Linux Commands Also if you’re working with Linux daily—what’s one command you use all the time? #Linux #DevOps #LearningInPublic #TrainWithShubham #90DaysOfDevops

We use Linux commands every day — but what really happens after pressing Enter? This visual breaks down the flow from shell input to process creation, program execution, output, and exit code. Understanding this makes concepts like PATH, fork/exec, stdout, and shell behavior much easier to grasp. #Linux #DevOps #SysAdmin #Programming #OpenSource #Terminal

Most people use the terminal… but it forgets everything. Every new session = starting over. That’s where environment variables come in. One of the most important is PATH. It tells your system: “Where should I look when I type a command?” So instead of running: ./hello-world.sh You can run it from anywhere: hello-world.sh All it takes is adding your folder: export PATH=$PATH:~/my-scripts Small change. Huge difference. #Bash #Linux #Terminal #DevOps #Programming CoderCo
