NAMEdu − estimate file space usage
SYNOPSISdu [OPTION]... [FILE]...
du [OPTION]... --files0-from=F
DESCRIPTION Summarize device 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 device 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 levels below the command line argument; −−max−depth=0 is the same as −−summarize −−files0−from=F summarize device 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 negative −−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, 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.
PATTERNSPATTERN 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).
