NAME
du, df - disk usage
SYNOPSIS
du [ -s ] [ -a ] [ file ... ]
df [ -i ] [ special ... ] [ file ... ]
DESCRIPTION
Du gives the number of Kbytes allocated to data blocks of
named files and, recursively, of files in named directories.
If name is missing, `.' is used. The count for a directory
includes the counts of the contained files and directories.
The options are
-s Print only the grand total.
-a Print a count for every file in a directory. Normally
counts are printed only for contained directories.
A file which has two (hard) links to it is counted only
once. Symbolic links are neither counted nor followed.
Df printsthe amount of free space on the file system con-
tained in special, or on the file system in which the speci-
fied file is contained. If no file system is specified, the
free space on all of the currently mounted file systems is
printed.
The reported numbers are in Kbytes, independently of the
blocksize actually used on the file system. The option is
-i Report also on free and used inodes.

ments to du are not listed.
If there are too many distinct linked files, du counts the
excess files multiply.
