@(#)du.1 6.3 (Berkeley) 05/08/89

.AT 3 du - summarize disk usage du [ -asx ] [ 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, the current directory is used.

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

The -x option keeps du from crossing any mount points.

A file which has multiple hard links to it is only counted (and displayed) once per du execution.
