Question

我有一些问题，我想阅读输入.txt文件参数并编写output.txt。我只能找到一行，我怎么能找到这个问题的所有行相同？当input.txt文件参数时删除，将删除output.file中的字符。

input.txt文件详细信息

write: 3 a 4 b 1 \n 2 d
delete: 1 a 2 b

output.txt将首先应用paramater结果

aaa bbbb 

dd

output.txt将应用第二个参数结果

aa bb

dd

试试这个（省略一些检查）：

FileUtils.cd('/home/ubuntu/projects/ruby-docker-heroku/blog')

require './config/boot'

require './config/environment'
