Rename Directory in Linux with mv Command

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

🚀 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

🐧 Most Linux beginners delete files they didn't mean to. Here's why 👇 3 commands. Infinite use cases. cp — Copy files without touching the original mv — Move OR rename (same command, different destination) rm — Delete permanently. No recycle bin. No undo. The trio every Linux user runs dozens of times a day — yet most skip the flags that make them safe: → Always use -i before you trust your path → Always use -r for directories → Never run rm -rf / — ever Once you internalize these 3, navigating your filesystem feels like second nature. 🐧 Which one did YOU accidentally misuse when starting out?

🚀 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

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

You use Linux… but do you actually understand what’s inside it? Everything in Linux starts here 👇 Most people use Linux daily, but very few actually understand its core structure. Here’s a simple breakdown of the Linux Directory Tree 🔹 Key Directories You Should Know: 📁 /bin – Essential user commands 📁 /sbin – System-level commands 📁 /etc – Configuration files (the brain 🧠) 📁 /home – User files & personal space 📁 /var – Logs, cache, dynamic data 📁 /usr – Applications & libraries 📁 /tmp – Temporary files #Linux #RHEL #Security #OS

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

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

I just posted [1] DAMON news letter for Linux 7.1-rc1 release cycle. We shipped two new features and two important internal improvements. Contributors are continuously making progress. Sashiko made us quite busy. [1] https://lnkd.in/gTZ2ex3E #linux #kernel #damon #release_news #7.1-rc1

⚙️ Linux Advanced Tip #2 – Track system calls with filtering Instead of full strace noise: strace -p <PID> -e trace=network,read,write Focus only on relevant syscalls. Useful for debugging slow APIs or network latency issues. #linux #debugging #sysadmin #devops
