Type the command that reports the total disk space consumed by /var/log including everything beneath it, as one single human-readable figure.
LPIC-1 Exam 101-500, objective 104. Devices, Linux filesystems, filesystem hierarchy standard medium
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
du walks a directory tree and adds up the space its files occupy. -s summarises: print one total for each argument instead of a line per subdirectory. -h prints sizes with K, M and G suffixes. Contrast df, which asks the filesystem itself how many blocks are allocated — that is why df counts space held by deleted-but-still-open files while du cannot see it.
Where this comes from
- Cited
- LPI exam objective 104.2
- What it says
- Report disk usage with du and free space with df.
Practise this
Reading one question is not practice. The trainer will draw a short set from objective 104 and space the ones you get wrong.

- A new disk /dev/sdb has no partition table at all. Which command writes an empty GPT partition table onto it without dropping you into an interactive editor? machine-checked
- You need the partition /dev/sdc1 on a USB stick to carry a FAT32 filesystem so that Windows machines can read and write it. Which command creates it? machine-checked
- You have just run `mkswap /dev/sdb2`. Which command makes the kernel start using that swap area immediately, without a reboot? machine-checked
- Why is it dangerous to run e2fsck against an ext4 filesystem that is currently mounted read-write? machine-checked
- On an ext4 filesystem at /dev/sda1 you want an automatic check to be forced after every 30 mounts. Which command sets that? machine-checked
- `df -h /var` reports the filesystem 100% full, but `du -sh /var` accounts for only about half that space. Nothing is hidden under a mount point. What is the most likely explanation? machine-checked
