du
DU(1) BSD General Commands Manual DU(1)
NAME
du -- display disk usage statistics
SYNOPSIS
du [-H | -L | -P] [-I mask] [-a | -s | -d depth] [-c] [-h | -k] [-x] [file ...]
DESCRIPTION
The du utility displays the file system block usage for each file argument and for each directory in the file hierarchy rooted in each direc-
tory argument. If no file is specified, the block usage of the hierarchy rooted in the current directory is displayed. If the -k flag is
specified, the number of 1024-byte blocks used by the file is displayed, otherwise getbsize(3) is used to determine the preferred block size.
Partial numbers of blocks are rounded up.
The options are as follows:
-H Symbolic links on the command line are followed, symbolic links in file hierarchies are not followed.
-L Symbolic links on the command line and in file hierarchies are followed.
-I mask
Ignore files and directories matching the specified mask.
-P No symbolic links are followed. This is the default.
-a Display an entry for each file in a file hierarchy.
-h "Human-readable" output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte
-r Generate messages about directories that cannot be read, files that cannot be opened, and so on. This is the default case. This
option exists solely for conformance with X/Open Portability Guide Issue 4 (``XPG4'').
-s Display an entry for each specified file. (Equivalent to -d 0)
-d depth
Display an entry for all files and directories depth directories deep.
-c Display a grand total.
-k Display block counts in 1024-byte (1-Kbyte) blocks.
-x File system mount points are not traversed.
The du utility counts the storage used by symbolic links and not the files they reference unless the -H or -L option is specified. If either
the -H or -L options are specified, storage used by any symbolic links which are followed is not counted or displayed.
Files having multiple hard links are counted (and displayed) a single time per du execution.
ENVIRONMENT
BLOCKSIZE If the environment variable BLOCKSIZE is set, and the -k option is not specified, the block counts will be displayed in units of
that size block. If BLOCKSIZE is not set, and the -k option is not specified, the block counts will be displayed in 512-byte
blocks.
