這個是我幾年前寫的, 用來自動設定好新的機器
雖然現在回頭看寫得很鱉腳, 但當時也幫我順利搞定了上百台新 server
你可以修改一下 disks 這個變數, 來指定要初始化哪些硬碟
注意它會格式化硬碟, 最好當參考就好, 或一定要看懂以後再使用
我也不能保證這是當初順利運作上百台的版本..

<pre class="c" name="code">

function make_partition {
    echo "use fdisk create ${1}1"
    /sbin/fdisk $1 &> /dev/null <<END_FDISK

把這段程式存成 xxx.bash
然後在 bash 底下這樣用:

<pre class="c" name="code">source xxx.bash
make_disk
