How to change permissions? Solved

Question

Hello,

I am looking to change the permissions for the "file system" so that it is not read-only but allows for read and write access.

I am new to Linux and I don't know the appropriate command.

Have a good day,

(I am using Edubuntu)

Configuration: Windows XP Firefox 2.0.0.6

terminal: sudo nautilus >>> password >>> the explorer is launched in root mode >>> Right-click on the media, properties, permissions... Set the owner to "your name" and set the rights to something like read write and all that, confirm the changes and launch Nautilus in user mode to check. (ubuntu logo, shortcuts, the desired disk. You should be able to do whatever you want from then on.

:D

The procedure is good for all disks - ntfs, reiserfs, ext3, ext4 and blah.... Internal or external disks via usb or otherwise. USB flash drives, mp3 players and cameras, and all devices that mount as logical disks :P :)

Have fun :D

(it makes me so happy to bypass my mitten methods proposed everywhere :P )

Hello,

The command to edit permissions is chmod.

If you are new to Linux, you may not be accustomed to the very strict (but entirely justified) restrictions on read, write, and execute access for different types of users.

To learn more about the chmod command:

$man chmod # in your command prompt ;-)

https://fr.wikipedia.org/wiki/Chmod

It can be tempting to make your entire system writable and executable for all users (like Windows XP), so you won't be bothered by these restrictions anymore. In fact, it's better to get used to it because you quickly realize the fundamental security reasons that justify maintaining well-managed permissions rather than reverting to the all-permissive nature of Windows XP.

Thank you very much for all this information! :-)  But if it's better to leave the rights as they are, how should I proceed to extract an archive into a folder in the file system?

The principle is as follows:

If you know perfectly what you're doing, and you know it's necessary, you switch to root to manipulate the system files.

If you have any doubt, then you need to think it over :-P

That's why UNIX systems have so many restrictions on rights, and this is a fundamental difference with Windows: the system does what you want it to do. If you really want to delete a system file, all you have to do is say "yes, I know what I'm doing" (which means logging in as root (or superuser in French)).

In Windows, it's different. You have access to everything, but you can't modify it, or you're redirected, helped, you end up doing something else instead, etc. You are all the time in a kind of "root" without ever really being one.

Hello,

I'm reaching out about this topic because I have the same kind of problem. I followed your instructions, but when I'm in sudo mode and I try to change the permissions in the dropdown menu, the window closes. Do you have any idea what the problem might be?

Thank you
