@(#)du.1 6.1 (Berkeley) 04/29/85

.AT 3 du - summarize disk usage du [ -s ] [ -a ] [ name ... ] Du gives the number of kilobytes contained in all files and, recursively, directories within each specified directory or file name . If name is missing, `.' is used.

The argument -s causes only the grand total to be given. The argument -a causes an entry to be generated for each file. Absence of either causes an entry to be generated for each directory only.

A file which has two links to it is only counted once.

df(1), quot(8) Non-directories given as arguments (not under -a option) are not listed.

If there are too many distinct linked files, du counts the excess files multiply.
