du(1) |
 |
du − estimate file space usage
du [OPTION]... [FILE]...
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, −−kilobytes
deprecated, like −−block−size=1K
−l, −−count−links
count sizes many times if hard linked
−m, −−megabytes
deprecated, 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 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 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).
