du − estimate file space usage
du
[OPTION]... [FILE]...
du [OPTION]... --files0-from=F
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 environment 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 following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.
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).
