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
SIZE may be (or may be an integer optionally followed by) one of following: 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).
