You work as a Network Administrator for McNeil Inc. The company has a Linux-based network.
You have just created a directory named Sales on a file server. David, a Sales Manager, has to
use this directory to keep sales reports. David reports that he is unable to save his reports in the
directory.
When you list the directory using the LS command, you get the following result:
drwxr-xr-x 2 root root 2048 Jan 2 2006 Sales What is the most likely cause?

A.
David does not have the Write permission on the directory.

B.
David is working on his local computer’s login.

C.
The Sales directory has been deleted by accident.

D.
The Sales directory is not properly mounted.

Explanation:

The most likely cause of the issue is that David does not have the Write permission on the Sales
directory.
The listing of the directory shows that root is the owner of the Sales directory. The permissions on
the Sales directory are rwxr-xr-x. The permission character set has three sets of three permissions
that are Read, Write, and Execute. The first set, which is rwx, represents the
Read, Write, and Execute permissions to the owner of the file. The second set, which is r-x,
provides the Read and Execute permissions to the group root. The third set, which is r-x, provides
the Read and Execute permissions to other users.
In order to resolve the issue, you will have to make David the owner of the Sales directory. For
this, you will have to run the following command:
chown david sales
After becoming the owner of the directory, David will automatically get the Write permission, and
he will be able to store his files in the directory.
Setting permissions on files and folders in Linux

Answer option B is incorrect. As the listing shows that David is not the owner of the folder, this will
not make any difference.
Answer options D and C are incorrect. According to the question, the directory is properly listed,
and mounting or deletion is not an issue.
