Question

我正在编写一个shell脚本，为游戏冒雨的风险制作新的保存文件。我正在尝试这样做，以便可以将所有可用的解锁部分（例如成就，怪物日志，工件等）一次性添加到文件中，或者用户将能够选择哪些部分他们想要补充。我是编写shell脚本的新手，我不太清楚为什么我在运行到目前为止的操作时遇到错误 语法错误接近意外令牌`}' 我的剧本如果有人能向我解释为什么我收到错误，如何解决它，和/或如何改进我的脚本，我将不胜感激。如果重要的话，我也在Mac OS X上。这是我的剧本。

Answer 1

您的脚本有一些错误： - 第93行：elif [ $text = "2" ] then;应更改为elif [ $text = "2" ]; then - 如果bash中的命令必须有fi来关闭条件。你可以参考http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-6.html 希望这个帮助

Answer 2

在决定编写脚本之前，您应该对您正在编写的语言有基本的了解。即使是粗略阅读the documentation或任何how-to pages，也会告诉您if语句的正确语法。

除此之外，您的脚本中存在许多低效率。反引号运算符启动一个子shell，一个bash的新实例，所以这不一定是你想在循环中做110次的事情。

以下是您修复的几个较大问题。我建议调查functions以消除大量代码重复和条件嵌套。

mkdir ~/Desktop/ror_save_unlock_all

echo "This script takes ~/Library/Application Support/com.riskofrain.riskofrain/Save.ini and backs it up to ~/Desktop/ror_save_unlock_all/originalSave. It generates a new Save.ini that is built to your specifications, unlocking all items and achievements or just the ones you choose, and replaces the existing Save.ini with the new one." >> ~/Desktop/ror_save_unlock_all/README.txt
