How to find the free(available) memory for physical hard disk in linux machine, not a logical disk. Is there any shell script or command is available .

"dmesg" should show it when it prints out boot log's reported architecture. For redhat, it's also in /var/log/messages.

Also fdisk will do it, but that tends to be in sectors, not in GB, so a little interpretation is required. But it's also the most accurate.


Customer surveys are for companies who didn't pay proper attention to begin with.
