在 nautilus 中显示符号链接目标

Question 1

此目标可以通过 Nautilus Script 实现。

该答案的来源是问题的答案部分：如果我创建了一个文件夹的链接，那么如何在 Nautilus 中从该链接文件夹转到“真实”文件夹？

该脚本的来源如下：在 Nautilus 中打开链接目标。列出的依赖项是perl和zenity，但它们已默认安装。

脚本内容没有区别，但是在现在的 Ubuntu 版本中，Nautilus 脚本的位置路径更改为：~/.local/share/nautilus/scripts

1.创建脚本文件并使其可执行：

touch ~/.local/share/nautilus/scripts/"Open link target"
chmod +x ~/.local/share/nautilus/scripts/"Open link target"

2.编辑脚本文件：

gedit ~/.local/share/nautilus/scripts/"Open link target" &

3.粘贴下几行作为脚本的内容：

#!/bin/bash
#Title=Open-the-link-target-in-nautilus
#Title[fr]=ouvrir-le-repertoire-cible-dans-nautilus

4.保存文件，打开 Nautilus，右键单击某些符号链接，转到“脚本部分”，然后单击“打开链接目标”：

5.然后就会出现这个对话框：

恐怕如果您想在列表视图中添加新列，就必须更改并重新编译 Nautilus 的源代码。
