运行 bash 脚本时收到 EOF 错误

问：

我有一个 bash 脚本，它是一个简单的日历应用程序。每当我运行它时，只要我输入，脚本就会终止，并且我收到消息：

“./addtocalendar-jrussial.sh：第 104 行：语法错误：文件意外结束”

我不确定是什么原因造成的。我所有的括号、大括号、引号和 if-else 语句都关闭了。

这是我目前拥有的代码：

#!/bin/bash

# addagenda--Prompts the user to add a new event for the agenda script

agendafile="$HOME/.agenda"


isDayName()
{
    # Return 0 if all is well, 1 on error.
    case $(echo $1 | tr '[[:upper:]]' '[[:lower:]]') in
    sun*|mon*|tue*|wed*|thu*|fri*|sat*) retval=0 ;;
    * ) retval=1 ;;
    esac
    return $retval
}


isMonthName()
{
    case $(echo $1 | tr '[[:upper:]]' '[[:lower:]]') in
    jan*|feb*|mar*|apr*|may|jun*) return 0 ;;
    jul*|aug*|sep*|oct*|nov*|dec*) return 0 ;;
    * ) return 1 ;;
    esac
}


normalize()
{
    # Return string with first char uppercase, next two lowercase.
    /bin/echo -n $1 | cut -c1 | tr '[[:lower:]]' '[[:upper:]]'
    echo $1 | cut -c2-3| tr '[[:upper:]]' '[[:lower:]]'
}
