Not being an expert in Linux/Ubuntu, I had to install from scratch today and messed up w/file permissions.
The thing is that, when backing everything up before reinstalling, a couple of important documents couldn't be copied to the external drive, so I used
gksudo nautilus to be able to.
Now I've copied them back and I can't use them. They are locked, a lock icon appears on a corner and the original error message shows again.
Is there a graphical/easy way to set file permissions back to normal?
I've read about
chown and I would like to avoid them if possible. If there's no choice, can any of you please give me a quick example on how to use it?
Thank you so much Ub. Community!
