How to run multiple command in single command?

Dear Unix Guru,

I have several directories as below
/home/user/
dir1
dir2
dir3
Each directory has different size. I want to print each directory size (Solaris command du -hs .)

Can you please guide me how to achieve this?

Thanks
Bala

from /hom/user run this command
du -k | sort -nr | less

Try separating them with a semi colon
