Which command is used to display disk usage in a human-readable format?

• A. du -h
• B. df -h
• C. ls -lh
• D. Both du -h and df -h

Answer: (D)

The command used to display disk usage in a human-readable format can indeed be represented by both 'du -h' and 'df -h'. The 'du' command, which stands for "disk usage," is primarily used to estimate file space usage. When you use 'du -h', the '-h' flag makes the output human-readable, meaning it will provide sizes in a format that is easier to understand (e.g., showing sizes in kilobytes, megabytes, etc., instead of just bytes). On the other hand, the 'df' command stands for "disk free." It provides a report on the amount of disk space used and available on file systems. Using 'df -h' also outputs the information in a human-readable format, which again translates the sizes into a more understandable form with units like KB, MB, and GB. Thus, both commands serve distinct but related purposes and can output disk usage information in a way that is accessible and easy for users to read, making the option indicating both 'du -h' and 'df -h' as valid a correct choice.
