KSH中出现意外错误

Question

首先，我是一个大菜鸟，我已经学会了学习KSH。

我已经按照一些教程进行了操作，然后我开始使用这段代码：

#!/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 

现在我有一个错误：

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

我做错了什么？你有什么想法吗？

此外，

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

我正在使用redhat。

看起来你在那里缺少'fi'。
