    NAME

    
    
    du
    
     - display disk usage statistics
    
     
    

    SYNOPSIS

    [-H | L | P ] [-a | s | d depth ] [-c ] [-h | k | m ] [-n ] [-x ] [-I mask ] [file ... ]  

    DESCRIPTION

    The utility displays the file system block usage for each file argument and for each directory in the file hierarchy rooted in each directory argument. If no file is specified, the block usage of the hierarchy rooted in the current directory is displayed.

    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 St -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.
    -m
    Display block counts in 1048576-byte (1-Mbyte) blocks.
    -n
    Ignore files and directories with user ``nodump'' flag (UF_NODUMP ) set.
    -x
    File system mount points are not traversed.

    The 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 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.
