Du (Unix)
du (abbreviated from disk usage) is a Unix computer program to display the amount of disk space used under a particular directory or files on a file system.
du counts the disk space by walking the directory tree. As such, the amount of space on a file system shown by du may vary from that shown by df if files have been deleted but their blocks not yet freed.
In Linux, it is a part of the GNU Coreutils package.
The du utility may first have appeared in version 3 of AT&T UNIX .
