In order, which set of Linux permissions are least permissive to most permissive?
- 777, 444, 111
- 544, 444, 545
- 711, 717, 117
- 111, 734, 747
Linux permissions are read numerically as “owner, group, other.”
The numbers stand for read: 4, write: 2, and execute: 1. Thus, a 7 provides that person, group, or other with read, write, and execute. A 4 means read-only, a 5 means read and execute, without write, and so on. 777 provides the broadest set of permissions, and 000 provides the least.
