DU(1)DU(1)NAMEdu - summarize disk usage
SYNOPSISdu [ -p ] [ -l ] [ -s ] [ -a ] [ name ... ]
DESCRIPTION
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.
A file that's the target of links is normally counted once, in the
first directory that is traversed. The -p option changes this
accounting to spread the file across all of its directories by causing
only 1/nth of the file to be counted per occurrence in a directory,
where n is the number of references to the file.
The -l option restricts searches to the file system containing name.
The -s option causes only the grand total to be given. The -a option
causes an entry to be generated for each file. If neither -s or -a is
specified, an entry is generated for each directory only.
SEE ALSOdf(1), quot(8)BUGS
Unless the -a option is specified, du ignores non-directory names.
If there are too many distinct linked files, du counts the excess files
multiply.
If multiple names are specified, then du forks a separate process to
handle each additional one. Because these processes don't share
information, linked files might be counted more than once. For
example, you can get different information from `du *' than from `du
.'.
