XK0-006 System Management Practice Question
Which command would display the disk usage of each file and directory in /home in a human-readable format, but only showing one level deep?
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
✓
du -h --max-depth=1 /home
du -h --max-depth=1 /home shows human-readable sizes for each item one level deep.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
du -h --max-depth=1 /home
Why this is correct
`du -h --max-depth=1 /home` satisfies both constraints: `-h` converts block counts to human-readable units (K, M, G), while `--max-depth=1` limits recursion to the immediate children of /home, excluding deeper subdirectories. This matches the requirement for per-file and per-directory usage at exactly one level.
- ✗
du -hs /home
Why it's wrong here
The -s flag summarises only a single total for /home, suppressing the per-directory breakdown the question requires. It is tempting because -h gives human-readable output, but -s suits a quick overall size check rather than listing each entry one level deep.
- ✗
du -h /home
Why it's wrong here
Shows all subdirectories recursively.
- ✗
df -h /home
Why it's wrong here
df reports filesystem-level space usage, not per-file or per-directory disk consumption, so it cannot show each entry in /home. It is tempting because -h gives human-readable output, but df suits checking mounted filesystem capacity, not directory usage.
