XK0-006 System Management Practice Question
Which command will display the disk usage of each directory in the current directory, in human-readable format?
⚠ Common exam trap
Watch out — candidates often confuse `df -h` (filesystem-level usage) with `du -h` (directory-level usage), often picking `df -h` because it also shows human-readable output.
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
The `du -h` command displays disk usage for each directory in the current directory, with the `-h` flag converting sizes into human-readable formats (e.g., K, M, G). This is the correct tool for per-directory disk usage reporting.
Answer analysis

du -h
Why this is correct

fdisk shows partition table, not disk usage.
