Access denied – Call ‘chmod’, May be ?

Have you ever experienced a message saying politely that you have no privileges to perform an action? I am pretty much sure that all of you may have that experience. Like for an example, suddenly your DB server stopped & you have to restart the server to continue your work, but the remote user which you are using has not the right access which Oracle ( DB user ) has ( Yes, We had faced a related situation recently! )

Since we are dealing with servers & most servers are Linux based machines, we need to figure a way to handle permission related things on Linux. So then our speaker, ‘chmod’ comes to action.

There are few things you needed to know before you proceed,

  • r   : Read permission
  • w  : Write permission
  • x   : Execute permission
  • +   : Adding permission
  •  –   : Revoking permission
