Linux File Permissions Explained by Yacquub Adan

🚀 Linux Tip: Find Command The find command is one of the most powerful tools in Linux to search files and directories. 🔹 Example: find /home -name "file.txt" 👉 Searches for file.txt inside /home directory 💡 You can also search by size, type, date, and permissions! #Linux #RHCSA #DevOps #SysAdmin #SkynetLinux

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

Curious—anyone else doing a monthly Linux self-assessment? Tracking my progress from basic terminal use to actually building and deploying real systems. It hits different when you treat Linux like an environment, not just a tool. Not perfect—but leveling up. If you’re doing the same, what are you measuring each month? 👉 Start here: https://lnkd.in/e4min8Hy #Linux #DevOps #SysAdmin #OpenSource #Fedora #Automation #TechGrowth #BayouFinds

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

Today I finally sat down and properly understood Linux permissions. I'd been cargo-culting chmod commands for a while without really knowing what the numbers meant. Turns out it's simpler than it looks: r = 4, w = 2, x = 1 — add them up for Owner, Group, and Others. That's it. chmod 750 means the owner gets full access, the group can read and run, and everyone else gets nothing. Once that clicked, everything else made sense. I wrote it up as a short note for myself — maybe it helps someone else too: 👉 https://lnkd.in/gpZNCGyN #Linux #LearningInPublic #TIL #DevOps

🚀 Linux recap – Day 2 🐧 It was all about users and permissions — something that looks simple but is actually very important. I went through how Linux manages users and groups, and how access is controlled for files and directories. Covered: - Users & groups basics - File permissions (read, write, execute) - Commands like "chmod", "chown" - Understanding ownership (user, group) - Basic idea of how permissions impact security At first, permissions looked confusing, but after practicing a bit, it started making sense. #Linux #DevOps #CloudLearning #LearningInPublic #LinuxBasics

🚀 NEW on We ❤️ Open Source 🚀 Reliable backups require more than a script. In this tutorial, Learn Linux TV shows how to build automated Linux backups with rsync, systemd timers, and Healthchecks.io monitoring. The result is a practical workflow that preserves previous versions, checks mount points, and alerts you when backups fail. https://lnkd.in/eC9A7whh #WeLoveOpenSource #Linux #OpenSource #SysAdmin #DevOps

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
