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
write counts for all files, not just directories
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
equivalent to ‘--apparent-size
produce a grand total
dereference FILEs that are symbolic links
summarize disk usage of the NUL-terminated file names specified
in file F
--si, but also evokes a warning; will soon change to be
equivalent to --dereference-args ( -D)
print sizes in human readable format (e.g., 1K 234M 2G)
-h, but use powers of 1000 not 1024
count sizes many times if hard linked
dereference all symbolic links
don’t follow any symbolic links (this is the default)
end each output line with 0 byte rather than newline
do not include size of subdirectories
display only a total for each argument
skip directories on different file systems
-X FILE, --exclude-from= FILE
Exclude files that match any pattern in FILE.
--exclude= PATTERN Exclude files that match PATTERN.
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
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
--help display this help and exit
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
will skip all files and subdirectories ending in
.o (including the file
