我在运行相当大的脚本时遇到问题。在输出中说:CASE - 意外标记附近的sythax错误

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" ;;' 

我不想让你做这lonng(脚本计数260线),所以我将只发布相关的部分:

echo -e "\e[0;32m First we will check if you have ssd or hdd drive \e[0m" 
ssd_check="$(cat /sys/block/sda/queue/rotational)" 
case "$ssd_check" in 
    "0") echo -e "\e[0;32m you have ssd drive, so we will optimaze that \e[0m" ; 
     # noatime 
     #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" ;

     gksudo xed /etc/fstab ;

     echo -e "\e[0;32m Now we will change trimming from weekly to daily schedule in cron \e[0m" ;

     echo -e "\e[0;32m Now we will chaeck if the swap limit is set to correct value for not overusing SSD \e[0m"

     if [ "$swap_check" -gt 1 ]; then 
       #MANUAL VERSION v 
       echo -e "\e[0;32m Swap limit is set to "$swap_check" which is to high. We have to reduce it to 1 \e[0m" 
       echo -e "\e[0;32m To do so, we will open /proc/sys/vm/swappiness file and please write those two lines at the end of this file: \e[0m" 
       echo -e "\e[0;32m # Sharply reduce the inclination to swap \e[0m"

输出说,这是相关的东西到我的主要案例。我无法弄清楚这有什么问题。我已经尝试了“0”)和“1”),并且也括在括号中,但是我得到了同样的错误。

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" ;; 

"0")关闭您的第一个块。
