Summarize disk usage of each FILE, recursively for directories. |

-a, --all |

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 |
|||
-b, --bytes |
|||
equivalent to `--apparent-size --block-size=1' |

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:

--help

--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).
