Explanation
Before explaining, I need to flag an error in this question's answer key.
The stated requirements do not match option B.
Breaking down what the question actually asks for:
- Owner: full privileges (rwx) = 7
- Group: read-only (r--) = 4
- Others: no permissions (---) = 0
That maps to chmod 740 - which is not among the choices.
What the choices actually do:
| Option | Owner | Group | Others | Match? |
|---|---|---|---|---|
A. chmod 444 | r-- | r-- | r-- | No - owner lacks write/execute |
B. chmod 760 | rwx | rw- | --- | No - group gets write, not read-only |
C. chmod 700 | rwx | --- | --- | No - group gets nothing |
D. chmod 644 | rw- | r-- | r-- | No - owner lacks execute; others can read |
The correct command for the described requirements is chmod 740, which isn't listed. Option B (chmod 760) gives the group read+write (6), not read-only (4) as specified.
Memory tip: In octal permissions, the three digits represent Owner | Group | Others. Each digit sums r=4, w=2, x=1. "Read-only" = 4 alone, never 6.
This appears to be a flawed exam question - if you encounter it on a test, be aware the intended answer is likely B due to the question designer confusing 6 (rw) with 4 (r).
