Instead of writing
而不是写作
File.open("foo.txt", "w"){|f| f.write("foo")}
We can write it
我们可以写出来
File.write("foo.txt", "foo")
Is there simpler way to write this one?
有没有更简单的方法来写这个？
File.open("foo.txt", "a"){|f| f.write("foo")}

这已经得到了很好的回答：
can you create / write / append a string to a file in a single line in Ruby
你可以在Ruby中一行创建/写/附加一个字符串
File.write('some-file.txt', 'here is some text', File.size('some-file.txt'), mode: 'a')
File.write（'some-file.txt'，'here is some text'，File.size（'some-file.txt'），mode：'a'）
