NAME
du - summarize disk usage
SYNOPSIS
du [ -a ] [ -r ] [ -s ] [ filename ... ]
DESCRIPTION
Du gives the number of kilobytes contained in all files and
(recursively) directories within each specified filename, if
filename is a directory. If a filename argument is a
regular file, the size of the file will be given only if one
or more options is given. The count includes the indirect
blocks of the file. If filename is missing, `.' is used.
Absence of an option causes an entry to be generated for
each directory only.
OPTIONS
-a Causes an entry to be generated for each file.
-r Messages will be generated when directories cannot be
read, files cannot be opened, etc.
-s Causes only the grand total to be given.
EXAMPLES
The following invocation gives the total disk usage for the
directory /tmp.
du -s /tmp
