如何通过标签搜索文件？

我可以使用 nautilus 标记文件，但目前还没有找到通过标记查找文件的解决方案。Tracker-search-tool 不提供标记搜索功能，Nautilus 也不提供，我所知道的其他任何应用程序也不提供。刚刚升级到 11.04。

答案1

它被称为跟踪器标签：

http://manpages.ubuntu.com/manpages/natty/man1/tracker-tag.1.html

它由 tracker-utils 包提供，该包是跟踪器工具的命令行版本。

-s -- lists all files associated with a tag
-a -- Add a tag to a file

例子

要添加标签：

tracker-tag -a TAG file

按标签搜索：

tracker-tag -s TAG
Result: 1
  /home/sean/file

来自我的系统的真实世界示例

<sean@mymachine:~> tracker-tag -a TAG exten
<sean@mymachine:~> tracker-tag -a testing atreides master.ldif php_error.log TrainingUpdates.otl

<sean@mymachine:~> tracker-tag -s testing
Results: 5
  /home/sean/TrainingUpdates.otl
  /home/sean/atreides
  /home/sean/exten
  /home/sean/master.ldif
  /home/sean/php_error.log

<sean@mymachine:~> tracker-tag -a myTagExample TrainingUpdates.otl atreides exten master.ldif php_error.log 
<sean@mymachine:~> tracker-tag -s myTagExample
Results: 5
  /home/sean/TrainingUpdates.otl
  /home/sean/atreides
  /home/sean/exten
  /home/sean/master.ldif
  /home/sean/php_error.log

<sean@mymachine:~> tracker-tag -s TAG
Result: 1
  /home/sean/exten

gnome-team ppa 中的 Nautilus 有一个用于添加和删除标签的插件，bun nof 用于搜索。当我向 nautilus 团队请求新的面板视图时 (https://bugzilla.gnome.org/show_bug.cgi?id=670163)得到了这个答案。

- the interface that allows to add tracker tags from Nautilus is not part of
Nautilus, but it's an extension
- we will not add any additional side pane, since we intentionally trimmed them
down to Places and Tree for Nautilus 3.0
- I think the best way to do what you want is from Tracker itself; if the UI
utilities shipped with Tracker don't allow you to do this, you should file a
bug against Tracker for it

所以我专门为此制作了一个 nautilus-python 扩展。安装 python-nautilus 并提交到跟踪器https://bugzilla.gnome.org/show_bug.cgi?id=670643

sudo apt-get install python nautilus

然后复制下一个代码并保存在 .local/share/nautilus-python/extensions/[filename].py 下

            tip="Etiketa iragazkia"
        )
        P.connect('activate', self.ojo, window)
        return [P]

最后重新启动 nautilus

nautilus -q

当您右键单击任何文件或在后台时，会出现一个新菜单项“Etiketa iragazkia”（巴斯克语标签过滤器）。

答案3

使用 tracker-tag 从命令行搜索标签。上述搜索语法在我的系统 (12.04) 上不起作用。“-s”选项仅适用于“--list”：

tracker-tag --list -s [tag]

这更像是对第一个答案的评论，但我仍然缺少一些能够发表评论的代表 :-(
