Bash 用于创建符号链接的脚本正在我的变量中添加字符 ._ 以创建符号链接

Question

我正在使用下面的 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）在变量 $FILE 中添加了一个“._”，然后在符号链接中使用它。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

只看每 4 行的末尾。请参阅 ._PlexStrangerThingsPreroll.mp4，然后再参阅 ._PlexSnowPreroll.mp4 ._Plex preroll 6F.mp4

._ 不应该出现在那里。

我正在使用 ubuntu 18

谢谢@JNevill，你是对的。这些文件来自 MacOS 到 Ubuntu。我没有意识到 MacOS 会创建这些隐藏文件。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 "._*" $ 添加到脚本时，它会忽略这些文件。

下面是更新后的脚本。

#/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，我忘了在我的原文 post 中说我最初从以下位置获得此脚本：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，我已经创建了说明来实现此脚本的预期目的：https://www.reddit.com/r/PleX/comments/fyoqh4/randomizing_prerolls_on_linux/
