The usermod command is a tool for updating details about an existing user account in your system. It's kind of like editing the "profile" of a Linux user. With it, you can adjust anything from the username to the login shell, without needing to delete and recreate the account.

XDA ☛ I tried running Proxmox inside a Docker container
Unlike other virtualization platforms, Proxmox is extremely versatile – to the point where you could mold your PVE setup to your liking. With all the community scripts floating around, it’s possible to fine-tune every aspect of your Proxmox workstation – be it the LXCs and VMs or even the host PVE instance. Plus, since it’s fairly lightweight, you could install Proxmox on practically any setup and still expect reliable performance on container-heavy workloads.
All these aspects considered, I came up with a terrible shower thought: what if I tried to run Proxmox inside a container? I’ve previously configured a Proxmox VM running in VirtualBox using nested virtualization, but deploying it as a containerized environment seemed even more ridiculous. Turns out, Proxmox works surprisingly well inside a container, and while it’s not the ideal way to set up a PVE node, it’s still a decent workaround if you wish to tinker with the virtualization platform without relegating a PC to it.

HowTo Geek ☛ 4 Effective Ways to Launch Apps From the Terminal
You've probably started an application from the terminal at some point, but did you notice that it keeps your terminal occupied until you close the application? That can be pretty annoying. Sometimes, though, it's useful to launch applications this way—I explain how I do it effectively.
Some people use menus, others use launchers—I personally launch all applications, like Firefox, from the terminal. This habit goes back to my earliest days using Linux (about 15 years ago), when I didn't know how to create shortcuts. Over time, I grew accustomed to launching applications this way, and since I always have a terminal window open, it just makes sense. Plus, I'm too lazy to set up and maintain a launcher configuration. With the terminal, I can fuzzy search my applications like a launcher, but with the added benefit of editing commands before launching them.

HowTo Geek ☛ 7 Ways to Use the ip Command When Networking on Linux
Ever wondered what the Linux ip command might be able to do for you? Maybe you're just getting into Linux terminal work or network management. Let me walk you through some basic examples of the ip command at work.
The ip command is a CLI tool for managing network devices, interfaces, tunnels, and routing. You can both view and manipulate those elements of your network with the ip command, changing at least how the device you're using sees those elements.
Keep in mind that none of the changes you make with the ip command following these examples are permanent. This makes the command nice in that if you make a mistake and destroy your device's connection to the network, you can right yourself just by rebooting. The other side of that coin, though, is that any persistent changes you're trying to make will require other commands.

HowTo Geek ☛ How I Created the Ultimate Rescue Drive for My PCs
Imagine this: you come home, turn on your PC or laptop, and it won’t boot. Now what? You had important work to do. Panic sets in, and you don’t know what to do next.
Now imagine this instead. You have a flash drive loaded with a Windows installer, a Linux OS that can run from the flash drive, and a couple of diagnostic tools. Suddenly, you’re not stuck staring at a blue screen of death. You’ve got a way forward.
