.SH DESCRIPTION

\fIDu\fR examines one or more directories and prints the amount of space 
 | 
						|
occupied by the files in those directories and their subdirectories.
 | 
						|
.SH BUGS
 | 
						|
\fIDu\fR calculates disk usage based on file size. It could be there
 | 
						|
are holes in the file, not occupying any actual disk blocks, causing
 | 
						|
\fIdu\fR to overestimate disk usage. (\fIDu\fR does recognize and correctly
 | 
						|
calculate disk usage when hard links are encountered.)
