DU(1)                 User Commands                 DU(1) NAME        du - estimate file space usage SYNOPSIS        du [OPTION]... [FILE]...        du [OPTION]... --files0-from=F 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 only symlinks that are listed on the command line        --files0-from=F           summarize     disk usage of the NUL-terminated file names specified           in file F; If F is - then read names from standard input        -H     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        -m     like --block-size=1M        -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 file systems        -X, --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        --time show time of the last modification of any file in the directory,           or any of its subdirectories        --time=WORD           show  time  as WORD instead of modification time: atime, access,           use, ctime or status        --time-style=STYLE           show times using style STYLE: full-iso, long-iso,     iso,  +FORMAT           FORMAT is interpreted like ‘date’        --help display this help and exit        --version           output version information and exit        Display     values     are  in  units     of  the  first     available  SIZE  from        --block-size, and the DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE  environ-        ment  variables.      Otherwise,  units  default  to 1024 bytes (or 512 if        POSIXLY_CORRECT is set).        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).
