NAME | |
du - estimate file space usage | |
SYNOPSIS | |
du [OPTION]... [FILE]... | |
du [OPTION]... --files0-from=F | |
DESCRIPTION | |
Summarize disk usage of the set of FILEs, recursively for directories. | |
Mandatory arguments to long options are mandatory for short options too. | |
-0, --null | |
end each output line with NUL, not newline | |
-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 | |
scale sizes by SIZE before printing them; e.g., '-BM' prints sizes in units of | |
1,048,576 bytes; see SIZE format below | |
-b, --bytes | |
equivalent to '--apparent-size --block-size=1' | |
-c, --total | |
produce a grand total | |
-D, --dereference-args | |
dereference only symlinks that are listed on the command line | |
-d, --max-depth=N | |
print the total for a directory (or file, with --all) only if it is N or fewer lev‐ | |
els below the command line argument; --max-depth=0 is the same as --summarize | |
--files0-from=F | |
summarize disk usage of the NUL-terminated file names specified in file F; if F is | |
-, then read names from standard input | |
-H equivalent to --dereference-args (-D) | |
-h, --human-readable | |
print sizes in human readable format (e.g., 1K 234M 2G) | |
--inodes | |
list inode usage information instead of block usage | |
-k like --block-size=1K | |
-L, --dereference | |
dereference all symbolic links | |
-l, --count-links | |
count sizes many times if hard linked | |
-m like --block-size=1M | |
-P, --no-dereference | |
don't follow any symbolic links (this is the default) | |
-S, --separate-dirs | |
for directories do not include size of subdirectories | |
--si like -h, but use powers of 1000 not 1024 | |
-s, --summarize | |
display only a total for each argument | |
-t, --threshold=SIZE | |
exclude entries smaller than SIZE if positive, or entries greater than SIZE if neg‐ | |
ative | |
--time show time of the last modification of any file in the directory, or any of its sub‐ | |
directories | |
--time=WORD | |
show time as WORD instead of modification time: atime, access, use, ctime or status | |
--time-style=STYLE | |
show times using STYLE, which can be: full-iso, long-iso, iso, or +FORMAT; FORMAT | |
is interpreted like in 'date' | |
-X, --exclude-from=FILE | |
exclude files that match any pattern in FILE | |
--exclude=PATTERN | |
exclude files that match PATTERN | |
-x, --one-file-system | |
skip directories on different file systems | |
--help display this help and exit | |
--version | |
output version information and exit | |
Display values are in units of the first available SIZE from --block-size, and the | |
DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE environment variables. Otherwise, units default | |
to 1024 bytes (or 512 if POSIXLY_CORRECT is set). | |
The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are | |
K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000). Binary prefixes can be | |
used, too: KiB=K, MiB=M, and so on. | |
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). | |
