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
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 li nked
-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 files that match PAT.
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
display this help and exit
output version information and exit
