The above command shows the size of the hda11 partiton. It is 68G. I have more partitions.

How do I find the size of the hda5 and hda6 partitions? What is the command? Your help is greatly appreciated.

you already have the size there, it's the end unit - start unit * unit size, e.g. for hda5 it's (4561 - 4553) * 8225280

acid_kewpie

hda5 has the following figures:

Start 4553
End 4561
Blocks 72261
Id 82

How did you calculate?
The figure 8225280 is not clear to me?
I want to know the size. As I wrote, hda11 is 68GB. I just want to know size in GB. I am interested in hda5 and hda6.

That's where that number comes from. You'll get an answer in bytes obviously, but you can easily convert that to gigabytes.

i just read it from the message you posted in the first place.

Thanks acid_kewpie and nylex for the replies.

The above figure applies to the entire harddrive. I am interested in hda5 and hda6.
I can't figure out it.

Do the calculation that Chris told you to do, namely

end unit - start unit
4553 4561

This is 8.
Unit size is 512.

8*512 = 4096

So the answer is 4096 bytes.

Am I correct? Please tell me.

*sigh* (4561 - 4553) * 8225280 = 65802240 bytes

Thanks acid_kewpie

So the largest free extended partition is hda6. I have installed Fedora Core 5 on hda11. I wouldn't touch it. I would install Mandriva on hda6.

I guess the following is the swap partition.
tmpfs 501M 0 501M 0% /dev/shm

Is it hda7, hda8, hda9 or hda10? How do I find it?

it's none of them, tmpfs is held in ram only.

Glad you people don't calculate my tax .... - try your math on hda8.
As for swap, you'd better hope you are using hda7 - you can check by issuing "swapon -s" from a terminal/console.
No point in all those (small) swap partitions.

On my system, the blocks column in fdisk -l /dev/sda is the near/same as size listed in qparted. This is also what shows from the command: cat /proc/partitions. So, it would seem that no calcutating is needed as I can easily see that all of my ext3 partitions are about 20GB and the swap is about 600MB. Just the way I made them.
Edit: I forgot to mention that fdisk -s or sfdisk -s also report partition size to be same as block in other commands.

Thanks for the replies.

[Nissanka@c83-250-99-43 ~]$ swapon -s
bash: swapon: command not found

[root@c83-250-99-43 Nissanka]# swapon -s

The swapon command did not work. How do I find my swap partition?

Mmmm - some crappy redhat derivative no doubt. Try either of these
