我不能处理这个问题。我运行脚本（我会在下面附上它），在第一个问题后，我得到错误“line 37 syntax error near unexpected token 'fi'如果fi被删除，什么都没有改变。帮助我理解...我尝试了许多解决方案，和dos2unix配置，并仔细检查了所有的缩进

# !/bin/bash

function pause (){
  read -p "Press any key to continue ... "
}
timedatectl set-timezone Atlantic/Reykjavik
a=`date +"%Y-%m-%d %H:%M:%S"`
echo -n -e "Current Date/Time is    " 
date
sleep 2
read -p "is it correct (Yes/No) ? " CC
  if [ "$CC" == "N" -o "$CC" == "n" ];then 
    echo "Exit testing ..."
    exit
  fi 
else
  read -p "Do you want to change (Yes/No) ? " CC
  if [ "$CC" == "Y" -o "$CC" == "y" ];then
    read -p "Please input new date, format: YYYYMMDD  " D
    NEWD="`echo $D | cut -b 1-4`"-"`echo $D | cut -b 5-6`"-"`echo $D | cut -b 7-8`"    
    read -p "Please input new time, format: HHMM   " T
    NEWT="`echo $T | cut -b 1-2`":"`echo $T | cut -b 3-4`":"00"    
    echo -n "date -s '" > d.sh
    echo -n "$NEWD $NEWT" >> d.sh
    echo "'" >> d.sh
    chmod 777 d.sh
    ./d.sh
    echo
    sleep 1
    clock -w
    sleep 1
    a=`date +"%Y-%m-%d %H:%M:%S"`
    echo -n -e "NEW Date/Time is""\e[0;32m $a\e[0m"", "
    read -p "Press ENTER to continue..."
  fi

UPD：enter image description here删除“else”后显示

UPD2***这是第二个出现相同错误的类似代码。另外，不要求输入信息（“请输入第一个MAC地址："）***
