The “du” command

Use this command to estimate how much disk space each specified file or subdirectory uses.

Specify one or more individual files or sub-directories by including the complete path to the desired item as a “<FILE or SUBDIRECTORY>” variable. Separate each entry with a whitespace. Output will summarize each “<FILE or SUBDIRECTORY>” variable entry as disk usage in bytes.
