怎么写格式化硬盘的shell脚本

coocal

我要把一个最小系统做到一张安装光盘上,在安装之前要求格式化硬盘并分区，该用什么工具，fdisk吗，问题是
fdisk是交互式的，有什么办法把它写成非交互式的吗。或者还有其他比fdisk更好的工具，听说
parted可以，但对它不熟悉。

如果只是格式化，不用分区，那么用mkfs就可以

parted 并不复杂

fog_proxy

可以用shell脚本实现

1. 
   
2. 
   
3. fdisk /dev/sda <<End
   
4. o
   
5. n
   
6. p
   
7. 1
   
8. 
   
9. 
   
10. t
    
11. c
    
12. w
    
13. End
    
14.

谢谢楼上两位回答，我试一下三楼的脚本
to sakulagi ：要求分区
