我在运行相当大的脚本时遇到问题。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" ;;'
我不希望你把它变成lonng（脚本计数260行）所以我只发布相关部分：

输出说这与我的主要案例有关。我无法弄清楚那是什么问题。我试过“0”）和“1”没有引号也在括号中，但我得到了同样的错误。
请帮忙！
