== NAME ==
du - estimate file space usage
== SYNOPSIS ==
du [OPTION]... [FILE]...
du [OPTION]... --files0-from=F
== DESCRIPTION ==
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.
PATTERNS
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).

NAME[edit]
du - estimate file space usage
SYNOPSIS[edit]
du [OPTION]... [FILE]... du [OPTION]... --files0-from=F
DESCRIPTION[edit]
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. PATTERNS 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).
