Who do I give my application to?

What are the ways to give permission to a group to use some application installed with root permissions?

• Is it the same as we give permissions for files and directories? Problem statement details: I have installed an application in root. Then I created a new group and added some users to that group. But now the users of this new group are definitely not able to use that application which I installed in root. How to give permission to this group to use that particular application?

• Answer:

  Yes, the permissions methodology is the same as what we apply to files and directories. But since its an application, the most important permission that it must have is 'execute (x)'. So even if you have installed an application as root, be sure to have the group read and execute permissions set for that particular executable and the directory it is in. For example: -rwxr-xr-x 1 root root 3063 Oct 5 15:07 update-locale
