NAME

       du - estimate file space usage


SYNOPSIS

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


DESCRIPTION

       Summarize disk usage of each FILE, recursively for directories.

       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     like  --si,  but  also  evokes a warning; will soon change to be
              equivalent to --dereference-args (-D)

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

       --si   like -h, 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

       -P, --no-dereference
              don’t follow any symbolic links (this is the default)

       -0, --null
              end each output line with 0 byte rather than newline

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

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

       -x, --one-file-system
              skip directories on different filesystems

       -X FILE, --exclude-from=FILE
              Exclude files that match any pattern in FILE.

       --exclude=PATTERN Exclude files that match PATTERN.

       --max-depth=N
              print the total for a directory (or file, with --all) only if it
              is   N   or  fewer  levels  below  the  command  line  argument;
              --max-depth=0 is the same as --summarize

       --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  fol-
       lowing: kB 1000, K 1024, MB 1000*1000, M 1024*1024, 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).
