DU

du − estimate file space usage

du [OPTION]... [FILE]...

Summarize disk usage of each FILE, recursively for directories.

−a, −−all

write counts for all files, not just directories

−−block−size=SIZE use SIZE-byte blocks

−b, −−bytes

print size in bytes

−c, −−total

produce a grand total

−D, −−dereference−args

dereference PATHs when symbolic link

−h, −−human−readable

print sizes in human readable format (e.g., 1K 234M 2G)

−H, −−si

likewise, but use powers of 1000 not 1024

−k, −−kilobytes

like −−block−size=1024

−l, −−count−links

count sizes many times if hard linked

−L, −−dereference

dereference all symbolic links

−m, −−megabytes

like −−block−size=1048576

−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 filesystems

−X FILE, −−exclude−from=FILE

Exclude files that match any pattern in FILE.

−−exclude=PAT

Exclude files that match PAT.

−−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

−−help

display this help and exit

−−version

output version information and exit
