du − summarize disk usage

This documentation is no longer being maintained and may be inaccurate or incomplete. The Texinfo documentation is now the authoritative source.
This manual page documents the GNU version of du. du displays the amount of disk space used by each argument and for each subdirectory of directory arguments. The space is measured in 1K blocks by default, unless the environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used.
OPTIONS
−a, −−all
Display counts for all files, not just directories.
−b, −−bytes
Print sizes in bytes.
−c, −−total
Write a grand total of all of the arguments after all arguments have been processed. This can be used to find out the disk usage of a directory, with some files excluded.
−k, −−kilobytes
Print sizes in kilobytes. This overrides the environment variable POSIXLY_CORRECT.
−l, −−count-links
Count the size of all files, even if they have appeared already in another hard link.
−s, −−summarize
Display only a total for each argument.
−x, −−one-file-system
Skip directories that are on different filesystems from the one that the argument being processed is on.
−D, −−dereference-args
Dereference symbolic links that are command line arguments. Does not affect other symbolic links. This is helpful for finding out the disk usage of directories like /usr/tmp where they are symbolic links.
−L, −−dereference
Dereference symbolic links (show the disk space used by the file or directory that the link points to instead of the space used by the link).
−S, −−separate-dirs
Count the size of each directory separately, not including the sizes of subdirectories.
|
−−help |
Print a usage message on standard output and exit successfully. |
−−version
Print version information on standard output then exit successfully.
On BSD systems, du reports sizes that are half the correct values for files that are NFS-mounted from HP-UX systems. On HP-UX systems, it reports sizes that are twice the correct values for files that are NFS-mounted from BSD systems. This is due to a flaw in HP-UX; it also affects the HP-UX du program.
