这个R用的非常赞，学习了
R filename
Queue a line of filename to be read and inserted into the output stream at
the end of the current cycle, or when the next input line is read. Note that
if filename cannot be read, or if its end is reached, no line is appended,
without any error indication.
As with the r command, the special value /dev/stdin is supported for the file
name, which reads a line from the standard input.
