Hi guys,
I want to write a script to automate partitioning for some project that I'm working on. I tried using fdisk but it was too painful... so, turned to sfdisk but now I'm getting strange results...or at least I think so.
What I want to do is, to get the disk size to be created from another script and create a partition of that size on the specific disk (also sent by the same script).
i.e. I want to create a partition with size of 5GB on /dev/hda.
First of all, do I need to convert GB to cylinders or blocks or sfdisk supports "GB" or "MB"?
Here's from my command prompt. Here's the strange thing that happens:
I have this:

Partition table entries are not in disk order

/dev/hdd5 7753 10859 1565896+ 83 Linux
and I want to add a new partition to /dev/hda:

Checking that no-one is using this disk right now ...
OK
Disk /dev/hda: 16644 cylinders, 16 heads, 63 sectors/track
Old situation:
Units = cylinders of 516096 bytes, blocks of 1024 bytes, counting from 0

Input in the following format; absent fields get a default value.
<start> <size> <type [E,S,L,X,hex]> <bootable [-,*]> <c,h,s> <c,h,s>
Usually you only need to specify <start> and <size> (and perhaps <type>).
/dev/hda1 :,,
/dev/hda1 0+ 16643 16644- 8388575+ 83 Linux
/dev/hda2 :
What happens is, when I want to keep the same size and everything for the rest of the partitions (by entering ",,"), it allocates the entire space for hda1...
What am I doing wrong guys? Please help!
Thanks
