The du command estimate file space usage and summarize disk usage of each
FILE, recursively for directories.
It displays the file system block usage for each file argument and for each
directory in the file hierarchy rooted in each direc tory argument. If no file
is specified it will use current directory.
But why use du command?
You must be wondering why I’m throwing out a light on du command. du is
commonly used by system administrators to automate monitoring and notification
programs that help prevent directories from becoming full.
