How to make files accessible only by root?
By Emma Martinez •
I'm using Ubuntu and I'm here to know is there any way to modify access of a specific application so that it can only root has access to it?
Currently that application can be launched by general users but I want to make it so that only root can do this.

Make sure that the owner of the application is root and set the permissions such that only the owner can run it.
sudo chown root:root /path/to/application
sudo chmod 700 /path/to/applicationIf you look now at permissions with ls -l /path/to/application, you should see the following: -rwx------ root root, meaning that root can read, write and execute, and anyone else cannot even read that file.
Change the permissions of this applications as a root :
chmod 700 application-nameMore in general
