How is setting the access permissions

I want to copy a file into my Root folder but I cant.
what should I do?

You speak of /root ???

This folder is owned by the root account so only the root user can change things here. So you must be root to copy a file.

Now the real question is why in the world would you want to copy or change anything in the /root directory??

Become root. Type

su -

and enter your root password when you are asked for it. Now you can copy (almost) anything anywhere. And you can do some very nasty things to your setup. Be careful and watch what you typed before hitting . When all is done enter


on the command line. You will be back being an ordinary user.

There are some reasons to edit things in /root. I keep my crontab config files there.
