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 FILEs that are symbolic links
- --files0-from=F
-
summarize disk usage of the NUL-terminated file names specified
in file F
- -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
- 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 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
- --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.
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).
