Need command to know the total size

:mad:i need command to know the total size of project in my system by Giga bit
i try
#du -s /*/projectname

but i need total size for this project by G.B

can you help me

use the "-h" option

You cannot force GB, but if you use du -sh to get an automatically scaled output, which is in GB, if the total size is between 1 GB and 1 TB (unless you have Solaris 9 or older, where the -h switch was not supported, as far as I remember).

du -sh /*/projectname
du: illegal option -- h
usage: du [-a][-d][-k][-r][-o|-s][-L] [file ...]
