Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
find /etc -perm /4000
The SUID bit is represented by the permission 4000. -perm /4000 checks if any of the bits in 4000 are set (SUID).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
find /etc -perm /4000
Why this is correct
Correct: /4000 matches files with SUID set.
- ✗
find /etc -exec ls -l {} \; | grep '^...s'
Why it's wrong here
This is a workaround but not the standard find method.
- ✗
find /etc -perm -4000
Why it's wrong here
-4000 matches files with all bits in 4000 set, which is more restrictive but also works for SUID. However, /4000 is more robust. In this context, /4000 is preferred because SUID is a single bit.
- ✗
find /etc -type f -perm 4000
Why it's wrong here
-perm 4000 matches exactly 4000, which requires other permissions to be zero.
