How can you determine the space occupied by a specific folder in a Linux system?

To determine the space occupied by a specific folder in Linux, the du (disk usage) command is used.

Example:

du -sh /path/to/folder

• -s — summarizes the total size of the folder without listing sizes of individual subfolders.
• -h — displays size in a human-readable format (KB, MB, GB).

To see the size of each subfolder:

du -h --max-depth=1 /path/to/folder

This shows the size of each first-level subfolder inside the specified directory.
