You want to get command of Linux block size so here is its some of other command:

-a, --all
write counts for all files, not just directories
-B, --block-size=SIZE use SIZE-byte blocks
-b, --bytes
print size in bytes
-c, --total
produce a grand total
-D, --dereference-args
dereference FILEs that are symbolic links
-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
like --block-size=1K
-l, --count-links
count sizes many times if hard linked
-L, --dereference
dereference all symbolic links
-S, --separate-dirs

-s, --summarize

-x, --one-file-system

-X FILE, --exclude-from=FILE

--exclude=PATTERN Exclude files that match PATTERN.
--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
