[请教]如何写这样的一个交互脚本?

呵呵,用shell,你会发现,dos就是垃圾啦  

1. 
   
2. read input?"please enter :"
   
3. case $input in
   
4. 1)     command1;;
   
5. 2)     command2;;
   
6. *)     echo "wrong input";;
   
7. esac
   

复制代码

用 select 也可啦, 而且它还能显示一个菜单

懒惰 ! 自己 help read 看看 !

/home/lee#cat input
#!/bin/bash
echo -n "please enter :"
read input
case $input in
1)     date;;
2)     pwd;;
*)     echo "wrong input";;
esac
/home/lee#bash input
