What commands do you use to monitor disk space usage?

The following commands are usually used to monitor disk space usage in Linux:

• df — shows information about free and used space on file systems. For example, df -h displays data in a human-readable format (with units).

• du — shows the size of specific files and folders.

Example usage:

df -h

Displays a list of all mounted file systems with information about size, used space, and available space.
