我当前正在努力制作一个使用Amazon AMI创建简单的EC2实例的云形式模板。创建此实例后，我将拥有一个UserData字段，该字段将在新实例中运行bash代码，以安装Jenkins，git，apache maven等，并更新路径变量和./bashrc文件。
我成功地完成了大多数这些要求，但是每当我尝试将任何内容回声到bashrc文件中时，它似乎都不起作用。我什至检查了运行BASH代码后生成的EC2实例中的日志文件，并且没有错误或任何问题。
这是我的整体云形式代码：

我什至仅使用Echo命令进行了测试，并且效果很好。如果我尝试将任何内容呼应到bashrc文件中，则无效。任何帮助将不胜感激。
我会尝试的几件事。
首先，您的脚本以root运行，因此不需要sudo命令。那不应该影响任何事情，但是您应该知道脚本在下面运行的用户。
第二，但与第一个有关，您是否正在寻找/root/.bashrc或/home/ec2-user/.bashrc中的更改？如果后者指定完整的路径。
