请看一下这段代码还能优化么？

1. echo -n "Enter Installation directory:"
   
2. read BaseDir
   
3. echo You enter Installation directory is:$BaseDir
   
4. echo "Confirm please enter [Yes],Enter again please enter [No]"
   
5. read affirm
   
6. affirm=`echo $affirm | tr A-Z a-z`
   
7. while [ "yes" != "$affirm" ];
   
8. do
   
9.         echo -n "Enter Installation directory"
   
10.         read BaseDir
    
11.         echo You enter Installation directory is:$BaseDir
    
12.         echo "Confirm please enter [Yes],Enter again please enter [No]"
    
13.         read affirm
    
14.         affirm=`echo $affirm | tr A-Z a-z`
    
15. done
    
16. echo $BaseDir

如果read 有-p 参数
echo xxx
read var
可以合并成一句

Iveon

我主要想说的是7-15行的内容.....

Iveon

我懂了，我犯了一个很白痴的错误。
上面那段不用写的.....

1. #!/bin/bash
   
2. while [ "yes" != "$affirm" ];
   
3. do
   
4.         echo -n "Enter VSB Installation directory"
   
5.         read BaseDir
   
6.         echo You enter VSB Installation directory is:$BaseDir
   
7.         echo "Confirm please enter [Yes],Enter again please enter [No]"
   
8.         read affirm
   
9.         affirm=`echo $affirm | tr A-Z a-z`
   
10. done
    
11. echo $BaseDir
