1.简介
该解决方案包含两个脚本-一个用于标记，一个用于读取特定标记下的文件列表。两者都必须~/.local/share/nautilus/scripts通过在Nautilus文件管理器中的任何文件上单击鼠标右键，然后导航到“脚本”子菜单来生存和激活。每个脚本的源代码都在此处以及上提供。 GitHub上
2.安装
两个脚本保存到~/.local/share/nautilus/scripts，那里~是用户的主目录，并提出可执行文件chmod +x filename。为了易于安装，请使用以下bash脚本：
#!/bin/bash
N_SCRIPTS="$HOME/.local/share/nautilus/scripts"
cd /tmp
rm master.zip*
rm -rf nautilus_scripts-master
wget https://github.com/SergKolo/nautilus_scripts/archive/master.zip
unzip master.zip
install nautilus_scripts-master/tag_file.py "$N_SCRIPTS/tag_file.py"
install nautilus_scripts-master/read_tags.py "$N_SCRIPTS/read_tags.py"
3.用法：
标记文件：
在Nautilus文件管理器中选择文件，右键单击它们，然后导航到“脚本”子菜单。选择 tag_file.py。单击“ Enter
首次运行此脚本”，将没有配置文件，因此您将看到以下内容：
下次，当您已经标记了一些文件时，您将看到一个弹出窗口，允许您选择一个标签和/或添加一个新标签（这样您可以将文件记录在多个标签下）。点击OK可将文件添加到此标签。注意：避免使用“ |” 标签名称中的符号。
该脚本将所有内容记录在中~/.tagged_files。该文件实质上是一个json字典（普通用户不必关心它，但是对程序员来说很方便:)）。该文件的格式如下：
{

"/home/xieerqi/Downloads/914549 -\u7ffb\u8bd1.txt"
]
}
如果您要“取消标记”某些文件，只需从该列表中删除一个条目即可。注意格式和逗号。
按标签搜索：
现在您已经有了一个不错~/.tagged_files的文件数据库，您可以读取该文件或使用read_tags.py脚本。
右键单击Nautilus中的任何文件（实际上无关紧要）read_tags.py。选择。击中Enter
您将看到一个弹出窗口，询问您要搜索的标签：
选择一个，然后单击OK。您将看到一个列表对话框，显示您希望所选标签存在的文件。您可以选择任何单个文件，它将以分配给该文件类型的默认程序打开。
