Du (Unix)
From Free net encyclopedia
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 first appeared in version 1 of AT&T UNIX.

Example
The -k flag will show the sizes in 1K blocks, rather than the default of 512 byte blocks.
$du -k /seclog 4 /seclog/lost+found 132 /seclog/backup/aix7 136 /seclog/backup 44044 /seclog/temp 439264 /seclog
