.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 in
|
|
kilobytes.
|
|
.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.)
