Linux Users and Permissions Explained

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

🚀 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

While `rsync` and `cp` appear to be similar on the surface, under the hood `rsync` is a more powerful tool for handling large transfers. Specifically, `rsync` handles incremental syncing and supports compression natively for large and/or repeated operations. The table below shows a side-by-side comparing both commands! #linux #commandline #mlops

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

Disk full. No downtime allowed. Now what? The answer is LVM — and every Linux Admin needs to master it. With just 3 commands, you can create, extend, and snapshot volumes on a live system: pvcreate /dev/sdb vgcreate myvg /dev/sdb lvcreate -L 20G -n mylv myvg No restarts. No data loss. No stress. ✅ Check out the full cheat sheet in the PDF above 👆 💬 Do you use LVM in production? Drop your tip below! #Linux #LVM #SysAdmin #DevOps #LinuxTips #StorageManagement #RHEL #OpenSource

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

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
