If a file has permissions set to 744, what access rights do the user, group, and world get?

In the context of file permissions, the notation "744" breaks down into three segments representing access rights for the owner (user), the group, and everyone else (world). Each digit corresponds to a set of permissions: read (4), write (2), and execute (1).

For "744":

• The first digit, 7, indicates that the user has all three permissions: read (4) + write (2) + execute (1), totaling 7.

• The second digit, 4, signifies that the group has read access only, which corresponds to the value of 4.

• The third digit, also 4, means that the world (everyone else) has read access only as well, similar to the group.

Therefore, the access rights can be summarized as follows:

• User: Read, Write, Execute (7)

• Group: Read (4)

• World: Read (4)

While the correct answer must accurately reflect that the user has full permissions, and both the group and the world have read access, the correct choice provides the precise breakdown. In this case, the answer that captures that detail provides the proper distribution of permissions across the user, group, and world as intended by the permission settings
