Automate fdisk

[root@RHEL5-VM ~]echo "n
p
1


w
"|fdisk /dev/hdb
[root@RHEL5-VM ~]# fdisk -l
"See the magic......"
With a for loop in place we can partiton and format any number of disks with in few minutes

for i in /dev/sda /dev/sdb /dev/sdc;do
echo "n
p
1


w
"|fdisk $i;mkfs.ext3 $i\1;done


PS:This particular sequence will create a single slice of the disk with maximum space.Try this only in test environments

You can make it more simple....

Add all the fdisk commands in one file...
e.g create a partition.txt with following contents:

Quote:

n
p
1


w

and then run it as follows:

Quote:

# for i in sda sdb sdc sdd ;do echo " *** partitioning disk /dev/$i ****";fdisk /dev/$i < partition.txt;done

This is useful in case of creating the same partitions on many disks, say you need to create single partition on all disks with available space..
