linux - get size of many files at once -

-

i've found can print list directories total size 

du -sb mydirectory

is there anyway can apply same command array of directories du -sb (mydirectory yourdirectory hisdirectory)?

just list dirs

du -sb mydirectory yourdirectory hisdirectory

note how man page says:

du [option]... [file]...

that's [file]... means.

if want examine directories in current directory

du -sb */
