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; althoughthe apparent size is usually smaller, it may belarger due to holes in ('sparse') files, internalfragmentation, 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 thecommand line
-d, --max-depth=,N/: print the total for a directory (or file, with --all)only if it is N or fewer levels below the commandline argument; --max-depth=,0/ is the same as--summarize
--files0-from=,F/: summarize disk usage of theNUL-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 negative
--time: show time of the last modification of any file in thedirectory, 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, 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). Forexample,*.owill match any files whose names end in.o.Therefore, the command

: du --exclude=aq*.oaq

will skip all files and subdirectories ending in.o(including the file.oitself).
