KSH出現意外錯誤

Question

首先，我是一個大白菜，而且我表示要研究KSH。

我按照一些教程，我站起身來驗證碼：

 
#!/bin/ksh 


print 
print "Please enter the type of " 
print "back you want done:[ABCD]." 

print "A: Daily" 
print "B: Weekly" 
print "C: Quarterly" 
print "D: Special" 

print 

print -n "Response: " 
read response 

print 

if [[ $response = [Aa] ]] 
then 
print "Starting daily backup" 

elif [[ $response = [Bb] ]] 
then 
print "starting weekly backup" 

elif [[ $response = [Cc] ]] 
then 
print "starting weekly backup" 

elif [[ $response = [Dd] ]] 
then 
print "starting special backup" 
print 
print "Please enter the type of " 
print "back you want done:[ABCD]." 

print "A: Daily" 
print "B: Weekly" 
print "C: Quarterly" 
print "D: Special" 

print 

print -n "Response: " 
read response 

print 

if [[ $response = [Aa] ]] 
then 
print "Starting daily backup" 

elif [[ $response = [Bb] ]] 
then 
print "starting weekly backup" 

elif [[ $response = [Cc] ]] 
then 
print "starting weekly backup" 

elif [[ $response = [Dd] ]] 
then 

print "starting daily backup" 

print 
print "please take out daily tapes." 
print "Please put in weekly tapes," 
print -n "and hit 'enter' to continue." 
read waiting 

print 
print "starting weekly backup" 

else 

print "'$response' is not a valid option." 
fi 

，現在我有一個錯誤：

 
./backup.ksh: line 18: syntax error at line 82: `then' unmatched 

什麼是我做錯了嗎？你有什麼主意嗎？

此外，

 
[someuser@5278752 ~]$ whereis ksh 
ksh: /bin/ksh /usr/share/man/man1/ksh.1.gz 

我使用紅帽。

看起來你在那裏缺少'fi'。
