bash - 案例-意外 token 附近的语法错误

Question

运行较大的脚本时出现问题。在中间输出说:

linuxMint_post-install.sh: line 131: syntax error near unexpected token `)'
linuxMint_post-install.sh: line 131: `    "1") echo -e "\e[0;32m you have hdd, skipping to the next step... \e[0m" ;;'

我不希望您将其拖长(脚本数260行)，所以我将只发布相关部分:

         #TODO add noatime automaticly with sed, use code bellow for check (look at I/O scheduler as example)
         echo -e "\e[0;32m fstab file will open in xed text editor. Add \"noatime,\" right before \"errors=remount-ro 0 1\" \e[0m" ;

         if [ "$swap_check" -gt 1 ]; then

              echo -e "\e[0;32m Swap limit is set to "$swap_check" which is to high. We have to reduce it to 1 \e[0m"

esac

输出说这与我的主要情况有关。我不知道这是怎么回事。我试过了“0”和“1”)，不带引号，也放在方括号中，但是出现相同的错误。

请帮忙!

更换

"1") echo -e "\e[0;32m you have hdd, skipping to the next step... \e[0m" ;;

通过

     ;;
"1") echo -e "\e[0;32m you have hdd, skipping to the next step... \e[0m" ;;

用 "0")关闭第一个块。
