我使用下面的bash脚本随机选择一个.mp4文件，并将其符号链接到应用程序(Plex(可以读取的另一个文件夹。问题是似乎(随机地(存在一个"_"添加到变量$FILE中，然后在符号链接中使用该变量。有什么想法吗？
脚本
#/bin/sh
rm -f /media/PATH_TO_PREROLL_THAT_PLEX_CAN_READ/preroll.mp4
find /media/joshua/Media/PlexPrerolls/ -maxdepth 1 -not -type d | sort -R | tail -1 | while read FILE; do
ln -s "$FILE" /media/PATH_TO_PREROLL_THAT_PLEX_CAN_READ/preroll.mp4 ;
done
Symlink检查
看看每4行的末尾。参见._PlexStrangerThingsPreroll.mp4，然后再参见._PlexSnowPreroll.mp4._Plex preroll 6F.mp4
__不应该出现在那里。

我正在使用ubuntu 18
谢谢@JNevil你说得对。这些文件是从MacOS到Ubuntu的。我没有意识到MacOS会创建那些隐藏的文件。每当我在目录中列出ls文件时，它们都不会显示。
当我将-not ( -iname "._*" )添加到脚本中时，它会忽略这些文件。
以下是更新后的脚本。
#/bin/sh
rm -f /media/PATH_TO_PREROLL_THAT_PLEX_CAN_READ/preroll.mp4
find /media/joshua/Media/PlexPrerolls/ -maxdepth 1 -not -type d -not ( -iname "._*" ) | sort -R | tail -1 | while read FILE; $
ln -s "$FILE" /media/PATH_TO_PREROLL_THAT_PLEX_CAN_READ/preroll.mp4 ;
done
此外，我忘了在我的原始帖子中说，我从以下地方获得了这个剧本：https://www.reddit.com/r/PleX/comments/arccd7/better_way_to_randomize_plexrolls/
如果有人因为搜索引擎或其他原因来到这里，我在这里创建了实现该脚本的说明：https://www.reddit.com/r/PleX/comments/fyoqh4/randomizing_prerolls_on_linux/
