bash而？循環選擇菜單

Question

#!/bin/bash 
echo "Please enter your Host Name" 
read hname 
echo "You have entered $hname, is this correct?" 
select yn in "Yes" "No"; do 
    case $yn in 
     Yes) sh runscript.sh; break;; 
     No) ; 
    esac 
done 

我該如何使這項工作，以便如果答案不正確回去再問一次？ 我知道我需要一個while循環來實現這一點，但不知道如何寫出來。

Answer 1

這應該做到這一點：

while [ "$yn" != "Yes" ]; do 
echo "Please enter your Host Name" 
read hname 
echo "You have entered $hname, is this correct? (Yes or No)" 
    read yn 
done 
sh runscript.sh 

Answer 2

這裏有另外一個你幫了我寫作：

#!/bin/bash 

     while ["$yn" != "Yes" ]; do 

    echo "Choose your type of installation" 

    echo "1) Home Media Server" 

    echo "2) Home Communication Server" 

    echo "3) Enterprise Communication Server" 

    echo "4) Hosting Server" 

    echo "5) Individual Packages" 

    echo "6) exit" 

    read case; 



    #simple case bash structure 

    # note in this case $case is variable and does not have to 

    # be named case this is just an example 



    case $case in 

     1) echo "You have entered Home Media Server, is this correct? (Yes or No)" 

     read yn 

       echo "Running script for Home Media Server";; 



     2) echo "You have entered Home Communication Server, is this correct? (Yes or No)" 

     read yn 

       echo "Running script for Home Communication Server";; 



     3) echo "You have entered Enterprise Communication Server, is this correct? (Yes or No)" 

     read yn 

       echo "Running script for Enterprise Communication Server";; 



     4) echo "You have entered Hosting Server, is this correct? (Yes or No)" 

     read yn 

       echo "Running script for Hosting Server";; 



     5) echo "You have entered $hname, is this correct? (Yes or No)" 

     read yn 

       echo "Running script for Individual Packages";; 



     6) exit 

    esac 

再次感謝。
