As a new Linux user, I've recently started learning about shells and scripting while manually installing Arch Linux. I'm a bit confused about the appropriate times to use 'sudo' and when it's not necessary. Could anyone explain the best practices regarding this? Any input would be greatly appreciated!

I take a rather strict approach: avoid using 'sudo' whenever possible. The system is pretty good about letting you know when you need admin permissions. If you find yourself unsure, just check if you're accessing or modifying system files or directories—if so, that's when 'sudo' comes in!
Mostly, you should only use 'sudo' for tasks that require it, such as compiling programs in '/usr/local/bin' or changing configurations in '/etc'. If you get a 'permission denied' error, that's your cue to use 'sudo'. But be mindful—not everything needs 'sudo', and it's usually safer to avoid it unless you have to. It's all about keeping your system secure!
You generally don't need to use 'sudo' for anything in your home directory. It's your personal space in Linux. But if you're making changes that affect the entire system, like editing files in the '/etc' folder or managing system services with systemctl, then you'll need to use 'sudo'. Think of it like needing admin rights on Windows!
In general, only use 'sudo' when you're altering system files or settings. It's like the administrator access in Windows—like when you modify files in program directories. For your own projects in the '/home' directory, you shouldn't need 'sudo' at all. But if your project requires changing critical files, then it's time to use 'sudo'. Just make sure you know what you're doing!
You'll need to use 'sudo' for tasks like running system processes, mounting filesystems, or managing packages. If you're not sure, you can check file permissions with `ls -l`. Files have specific permissions for users, groups, and others, and 'sudo' lets you access or modify files that your user account doesn't normally control. Just remember to be cautious with it, as running commands with 'sudo' as the root user can mess things up if you're not careful!
A good rule is to avoid using 'sudo' unless absolutely necessary. If you're just working on personal scripts or files in your home directory, you should be fine without it. Use 'sudo' primarily when you need to change system-wide configurations or run commands that require elevated permissions. Always be cautious, as using 'sudo' carelessly can lead to issues.
Yeah, I totally get that! I've made the mistake of just throwing 'sudo' in front of commands and it wrecked my file permissions. Now I'm more careful!
