推荐答案

您可以使用 shuf 。在一些系统上至少（似乎不是在POSIX）。

You can use shuf. On some systems at least (doesn't appear to be in POSIX).

正如jleedev指出： sort -R 也可能是一个选项。至少在一些系统上;好吧，你得到的图片。 已经指出， sort -R 不会真正随机播放，而是根据它们的哈希值对项进行排序。

As jleedev pointed out: sort -R might also be an option. On some systems at least; well, you get the picture. It has been pointed out that sort -R doesn't really shuffle but instead sort items according to their hash value.
