How does the --exclude=PATTERN option work in the du command?

The --exclude=PATTERN option in the du command is used to exclude files and directories that match a specified pattern from the disk usage calculation. This can be helpful when you want to focus on specific parts of a directory tree without including certain files or subdirectories.

Example Usage

du --exclude='*.log' -h /path/to/directory

In this example:

• --exclude='*.log' tells du to ignore all files that have a .log extension.
• -h provides the output in a human-readable format (e.g., KB, MB).
• /path/to/directory is the target directory you want to analyze.

Notes

• You can use wildcards (*, ?) in the pattern to match multiple files.
• This option is useful for excluding temporary files, logs, or any other files you don't want to include in the size calculation.
