如何连续轮询当前播放歌曲的 mpd 并将结果写入文件？

Question

我唯一需要从 mpd 中提取的是当前播放的 song/track。我必须确保这在输出文件中始终是最新的。

Answer 1

如果安装 mpc，则可以执行以下操作：

mpc idle player # block until the player changes songs
mpc current     # outputs "Artist Name - Song Name" onto stdout

循环执行这些，并将current的结果输出到文件中，你就完成了！

#!/bin/sh
while true
do
  mpc current > current_song.txt
  mpc idle player
done
