How can I give myself permission to delete a folder from "file system/opt"? Folder owner is root. I am the only user of this computer but I did not install the OS. I am not much of a tech person but can follow instructions.
First: do you really need to delete it?
Second: I would not recommend to use sudo. Instead I think it's better to always use gksudo. Why?:
You should never use normal sudo to start graphical applications as root. You should use gksudo (kdesudo on Kubuntu) to run such programs. gksudo sets HOME=~root, and copies .Xauthority to a tmp directory. This prevents files in your home directory becoming owned by root.
You can open a terminal,and type:
Press Enter and a new window will open. Now you can delete anything, included things that you should not delete!
You can do
sudo chown <username>:<username> /opt
but I probably will cause the system to not work correctly
it is not recommended to give yourself a permissions on the opt folder, this sometimes cause a security problems, so if you want to edit a file in the folder just run:
and edit the file ! :) thanks.
Issue the following in Terminal:
sudo rm /opt/name-of_folder_or_file
will immediately delete the named file or folder. Exercise this command with caution.
Press ALT-F2, then type:
sudo rm -rv /opt/INSERT-FOLDERNAME-HERE
This only works if you have sudo permission. (You must be an Administrator user)
