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, −−allwrite counts for all files, not just directories
−−apparent−sizeprint 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=SIZEuse SIZE−byte blocks
−b, −−bytesequivalent to `−−apparent−size
−−block−size=1'
−c, −−totalproduce a grand total
−D, −−dereference−argsdereference only symlinks that are listed on the command line
−−files0−from=Fsummarize disk usage of the NUL−terminated file names specified in file F
−Hlike −−si,
but also evokes a warning; will soon change to be
equivalent to −−dereference−args
(−D)
−h, −−human−readableprint sizes in human readable format (e.g., 1K 234M 2G)
−−silike −h, but use
powers of 1000 not 1024
−klike −−block−size=1K
−l, −−count−linkscount sizes many times if hard linked
−mlike −−block−size=1M
−L, −−dereferencedereference all symbolic links
−P, −−no−dereferencedon't follow any symbolic links (this is the default)
−−nullend each output line with 0 byte rather than newline
−S, −−separate−dirsdo not include size of subdirectories
−s, −−summarizedisplay only a total for each argument
−x, −−one−file−systemskip directories on different file systems
−X FILE, −−exclude−from=FILEExclude files that match any pattern in FILE.
−−exclude=PATTERNExclude files that match PATTERN.
−−max−depth=Nprint 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
−−timeshow time of the last modification of any file in the directory, or any of its subdirectories
−−time=WORDshow time as WORD instead of modification time: atime, access, use, ctime or status
−−time−style=STYLEshow times using style STYLE: full−iso, long−iso, iso, +FORMAT FORMAT is interpreted like `date'
−−helpdisplay this help and exit
−−versionoutput 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.
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).
The full documentation for du is maintained as a Texinfo manual. If the info and du programs are properly installed at your site, the command
info du
should give you access to the complete manual.
