Could someone tell me a command i can run on my Redhat machines to find out
the physical disk size of the hard disk in the machine without having to
take the disk out and look at it , this is because  i have some machines
that are 18/36/72/73 gig and need to know which ones they are. I have run a
fdisk to show the partitions but i am unsure if all of the machines have
been configured to use all of the disk so there must be a command i can run
to just check this out?
Any help would be much appreciated.
