DU(1) DOMAIN/IX SYS5 DU(1)
NAME
du - summarize disk usage
USAGE
du [ -ars ] [ names ]
DESCRIPTION
Du prints the number of blocks (1024 bytes per block) con-
tained in all files and directories specified by the names
argument. The block count includes the indirect blocks of
the file. A file with two or more links is only counted
once. If the names argument is missing, a period (.) is
used.
OPTIONS
-a Generate an entry for each file.
-r Generate messages about directories that cannot be
read, files that cannot be opened, etc. Du is
normally silent about such things.
-s Print only the grand total of blocks for each of
the specified names.
CAUTIONS
Absence of the -a or -s options causes an entry to be gen-
erated for each directory only.
If the -a option is not used, nondirectories given as argu-
ments are not listed.
If too many distinct linked files exist, du counts the
excess files more than once.
Files with holes in them will get an incorrect block count.
