How to check the free space available on the whole disk ?

Dear Van,

this is a different one,

[root@linuxbox ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda6 9.7G 414M 8.8G 5% /
/dev/sda1 99M 12M 83M 13% /boot
none 1014M 0 1014M 0% /dev/shm
/dev/sda3 9.7G 61M 9.1G 1% /opt
/dev/sda2 15G 1.9G 12G 14% /usr
/dev/sda5 9.7G 346M 8.8G 4% /var

fdisk -l
shows the entire physical hard disk space, regardless of whether a filesystem has been installed. You can calc how much is available as per previous posts.

df -h
show how much space is available in the filesystem layer on top of the physical disk.
The filesystem does not necessarily cover the entire physical disk, although this is unusual except during installation.

Has anybody mentioned this: fdisk -l and this: df -h before???

I have posted both the df -h and fdisk -l outputs.

How can we determine the remaining free space on the hard drive using the df -h and fdisk -l ?

I require the output of free space left on hard drive in GB.

Thanks

You have already been given the answers to your questions.

Please re-read this thread.

The reply by Contusion gives the answer, still it says the value in cylinders, which I also read, but I have to manually calculate the numbers and if it is for many systems, How can I found out?

"Based on your fdisk output of your 147GB hard disk there is still space left.
See the total cylinders of your hard disk is 17844. But your last partition ends on 15695 cylinder. So you still have 17844-15695 cylinders left"
