list.files（）目录和子目录中的所有文件

I'm trying to list all the files in a directories including subdirectories that end with _input.txt.

我正在尝试列出目录中的所有文件，包括以_input.txt结尾的子目录。

- folder 1
  - a_input.txt
  - folder 2
    - b_input.txt

If folder 1 were my working directory, I would like list.files(pattern = "\\_input.txt$") to be able to detect both a_input.txt and b_input.txt

如果文件夹1是我的工作目录，我希望list.files（pattern =“\\ _ input.txt $”）能够检测到a_input.txt和b_input.txt

To list the matching files in all subdirectories, you can use recursive = TRUE in list.files()

要列出所有子目录中的匹配文件，可以在list.files（）中使用recursive = TRUE

list.files(pattern = "_input.txt$", recursive = TRUE)
