运行Bash日历脚本时遭遇unexpected end of file错误求助

报错unexpected end of file是语法错误导致脚本解析中断，你脚本里的关键错误在第71行：

if [ ! isMonthName $word2 ] ;

这里写法有误，[ ]是test命令的语法，不能直接在其中调用自定义函数isMonthName。正确写法需去掉方括号，直接用逻辑非判断函数返回值：

if ! isMonthName "$word2" ;

修复后的完整代码 #

额外优化说明：

• 给所有变量引用添加双引号，避免空格或特殊字符引发的解析错误
• 拆分紧凑的case语句换行，提升代码可读性
