get the size of directory in AIX

If you have a directory structure made up a directory and sub directories (let us say 6) then the command that will give me the size of the entire directory structure can be calculated using following options,

ls -lR /your-directory | awk '{sum += $5}; END {print sum}'

you can also use du command,

du -sg /your-directory
