how do I pass or read values from file ?

Hi one & All ,

My Need is to Create 64 Partition and create File System in Linux.

I have the Script ...

for((a=0;a<=63;a++))
do
fdisk /dev/cciss/c0d$a
done

for((a=0;a<=63;a++))
do
mkfs.ext2 /dec/cciss/'c0d'$a'p1'
done


the moment I run the Script I get the Prompt ...

Command (m for help) : n ( is the value I Enter )
command action
e extended
p primary partition (1-4)

p ( is the Value I Enter)
partition number (1-4) : 1
First cylinder (1-251, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-251, default 251): 251
command ( m for help) :w

So as you see , I Basically provide 64 times the Values

n
p
1
1
251
w

please help ,is there way i can pass these Values in loop so I dont have to Enter Manually Smilie

I'm still @ Learning , so would be grateful if some GURU here helps Smilie

Regards

Put the things you type in a file (1 thing on 1 line) und use like

fdisk /dev/whatever < filename

Other option would be to use sfdisk (scriptable fdisk replacement) which is amoung other things able to "nuke in" a new partition table with one command.
