I'm trying to made an script that use FDisk to create partitions, but command like echo | fdisk not works, just hang the console and I need to kill de fdisk process.

This is the output

Code: Select all

root@antiX1:/home/Carlos# echo"p\nq\n"| fdisk /dev/sda
GNU Fdisk 1.2.4

Using /dev/sda

Any idea about this error?

Ok, I got it. I was using gnu-fdisk package (1.2.4). After remove it, fdisk use the binary that comes from util-linux.

Now the script works as expected.

Why antix comes with util-linux and gnu-fdisk?

Because at the time of release there was an issue with fdisk in util-linux. I can't remember exactly what.

I strongly suggest you use parted instead of fdisk for this kind of automation. It was designed to be automated so your scripts will be much less cryptic. If you are not certain parted will be available on your target systems then I suppose you will have to use fdisk.
