    There is a reason you can't do that! That's the whole point of file-permissions. You need to be root to write files into /usr/lib.

    If you are NOT root, then you can't write to /usr/lib, that's it! This is called "file protection", and most OS's have it. It's there so that normal user's can't mess the system up.

    So that executable propably has the suid bit set and runs with the rights of root.

    try
    Code:
    sudo cp -r /usr/lib/munna.txt /usr/lib/
    You should be know the root password to execute this command. Which distribution are u using?
