which user can override file permissions on a Linux computer? Understand the root user now.

Well, let me tell you, this Linux computer thing, it’s a real head-scratcher. But I heard somethin’ ’bout which user can override file permissions on a Linux computer. Sounds mighty important, don’t it?

So, this here thing called “root user”, that’s the big cheese. Like the boss of the whole dang computer. This root user, they can do whatever they want. Change this, change that, no problem. This root user can override file permissions. Like, if a file is locked up tight, root can just waltz right in and open it up.

Now, us regular folks, we ain’t got that kind of power. We can only mess with our own stuff. That is how it should be too! Unless someone gives us a little extra somethin’-somethin’. But that root user, they’re the king of the castle. They make the rules, you know?

They say this root user is for makin’ big changes to the whole system. Like fixin’ things when they’re broke, or addin’ new stuff. It ain’t for everyday use, no sir. Too much power for a regular person like me, I reckon. I surely do not want to mess with a computer!

• Root user is the boss.
• Root user can change anything, override file permissions.
• Regular users can only change their own files.

This whole Linux file permissions thing is like lockin’ up your chickens at night. You don’t want just anyone comin’ in and takin’ ’em, right? So you put a lock on the coop. That’s what these permissions do. They keep folks out of things they ain’t supposed to be in. And the Linux root permission, that is like the master key, it opens any lock, anytime. It is all about permissions to read, write and execute. Well, I do not understand it fully but that is what I heard.

I heard someone talkin’ ’bout somethin’ called “0755”. Said it’s the permissions for the root directory. Sounds like a bunch of mumbo jumbo to me. But they said it means the owner, this root fella, can read, write, and do somethin’ called “execute”. Whatever that means. I just nod my head when they talk about these things. I sure am not going to ask them what that means. They will think I am a fool!

Now, there’s these other folks, “ordinary users” they call ’em. That’s probably me and you. We can only change the permissions on files we own. Makes sense, right? Can’t go around messin’ with other people’s stuff. Unless, like I said, someone gives you the okay. Then you might be able to do a little more.

But this root user, they don’t need nobody’s permission. They can override any file ownership and permission restrictions. They’re like the sheriff in town, they can go anywhere and do anything. They got the keys to the whole kingdom. They are the superuser, that is what they call them. They got the power to do whatever they want with files on the computer. They can just walk into any place in the computer and open any file they want. No one can stop them.

• Permissions keep people out of things they shouldn’t be in.
• Ordinary users can only change permissions on their own files.
• Root user can change permissions on any file, that is what override file permissions means.
• Root is like a sheriff in the computer world.

It’s all very confusin’, this computer stuff. But the main thing to remember is this root user, they’re the one in charge. They can override file permissions, change things around, do whatever they need to do. Us regular folks, we just gotta stick to our own little corner of the computer and not cause any trouble. I sure do not want to be messing with things I do not understand. I may break the whole computer!

They was talkin’ about somethin’ called chattr too. If you use that thing, you can take away some of the root user’s power. I think it is crazy though. I do not know why someone would want to take away power from the most powerful person. That don’t make no sense to me. But what do I know about computers? I am just tellin’ you what I heard.

And somethin’ about ACE. I think that stands for “Access Control Entry”. I do not know what that means. All I know is that with ACE, you can give permission to a specific user. For example, you can give them permission to read and write. Maybe that is how ordinary users can do somethin’ more sometimes? I do not know for sure. Computers are too complicated.

So, to answer that question, which user can override file permissions on a Linux computer? It’s the root user. Plain and simple. They’re the boss, the head honcho, the big cheese. They got all the power. That is the only person that can do that. No one else can. Remember that and you’ll be alright. Just don’t go messin’ with things you don’t understand, especially them permissions. You might lock yourself out of your own computer!
