|DU(1)||General Commands Manual||DU(1)|
duutility displays the file system block usage for each file argument and for each directory in the file hierarchy rooted in each directory argument. Note that the system block usage is usually greater than the actual size of the file. If no file is specified, the block usage of the hierarchy rooted in the current directory is displayed. The options are as follows:
0has the same effect as
-s. Overrides earlier
-koption causes the numbers to be reported in kilobyte counts.
-k. Where more than one of these options is specified, the last option given overrides the others.
ducounts the storage used by symbolic links and not the files they reference unless the
-Loption is specified. If either the
-Loptions are specified, storage used by any symbolic links which are followed is not counted or displayed. The
-Poptions override each other and the command's actions are determined by the last one specified. Files having multiple hard links are counted (and displayed) a single time per
-hoption is specified.
duutility exits 0 on success, and >0 if an error occurs. df(1), fts(3), symlink(7), quot(8)
