SYNOPSIS

       du [OPTION]... [FILE]...


DESCRIPTION

       Summarize  disk usage of each FILE, recursively for direc­
       tories.

       Mandatory arguments to  long  options  are  mandatory  for
       short options too.

       -a, --all
              write counts for all files, not just directories

       --apparent-size
              print  apparent  sizes,  rather  than  disk  usage;
              although the apparent size is usually  smaller,  it
              may  be  larger  due  to holes in (`sparse') files,
              internal fragmentation, indirect  blocks,  and  the
              like

       -B, --block-size=SIZE use SIZE-byte blocks

       -b, --bytes
              equivalent to `--apparent-size --block-size=1'

       -c, --total
              produce a grand total

       -D, --dereference-args
              dereference FILEs that are symbolic links

       -h, --human-readable
              print sizes in human readable format (e.g., 1K 234M
              2G)

       -H, --si
              likewise, but use powers of 1000 not 1024

       -k     like --block-size=1K

       -l, --count-links
              count sizes many times if hard linked

       -L, --dereference
              dereference all symbolic links

       -S, --separate-dirs
              do not include size of subdirectories

       -s, --summarize
              display only a total for each argument

       --help display this help and exit

       --version
              output version information and exit

       SIZE  may be (or may be an integer optionally followed by)
       one of  following:  kB  1000,  K  1024,  MB  1,000,000,  M
       1,048,576, and so on for G, T, P, E, Z, Y.


PATTERNS

       PATTERN  is  a  shell  pattern (not a regular expression).
       The pattern  ?   matches  any  one  character,  whereas  *
       matches  any  string  (composed  of  zero, one or multiple
       characters).  For example, *.o will match any files  whose
       names end in .o.  Therefore, the command

              du --exclude='*.o'

       will  skip  all  files  and  subdirectories  ending  in .o
       (including the file .o itself).
