Managing disk space on a Linux system can be a breeze with the right tools. One of the best commands for this task is `du -sh *`, which lists file sizes in a human-readable format.

What is `du -sh *`?

• du: Disk Usage command.
• -s: Summarize disk usage for each file/directory.
• -h: Output in human-readable format (e.g., K, M, G).
• *: Wildcard to match all files and directories.

Output example

$ du -sh *

4.0K    file1.txt
16K     file2.txt 
1.5M    project 
200M    videos
