下面提供的脚本允许设置 GitHub 存储库图标或徽标（但不能同时设置），以及将元数据重置为默认值。使用方法非常简单，如选项所示-h：
$ ./set_folder_icon.py -h
usage: set_folder_icon.py [-h] [-i ICON] [-e EMBLEM] [-r ROOT] [-u]
Finds and sets github repository icons.Choose either --icon or --emblem.
Without either the script exists with 0 exit status.For --icons, use absolute
or relative path.For --emblem use single string of text.Emblem pathnames are
in the format emblem-name.extension.The script then can becalled with -e
<name>.Use ~/.local/share/icons folder for custom emblems (if it does not
exist - create it. Store filenames in specified format
optional arguments:
-h, --help show this help message and exit
-i ICON, --icon ICON path to image to set
-e EMBLEM, --emblem EMBLEM
single-string emblem name
-r ROOT, --root ROOT where search starts,default - current working
directory
-u, --unset unset both emblem and icon. Cannot be used with -e or
-i options
因此，如果我们想递归搜索主文件夹中的所有github存储库并设置它们的徽标，我们可以这样做，set_folder_icon.py -e myemblemname -r $HOME或者只是cd; set_folder_icon.py -e myemblemname
为了获得最佳性能，请创建~/bin目录并将脚本存储为set_folder_icon.py。如果您想立即使用它，请运行source ~/.bashrc。如果您使用的是其他 shell，请确保您的~/bin已添加到$PATH变量中。
笔记：脚本可以使用--icon选项获取任意文件，但--emblem要求您有一个要存储的特定文件，~/.local/share/icons文件名类似于emblem-github。请参阅脚本实际运行部分的示例

我碰巧将所有 GitHub 存储库保存在~/GIT文件夹下。在下面的屏幕截图中，您可以看到所有 GitHub 存储库的徽标如何设置为自定义徽标。

该脚本也可以在我的个人 GitHub 仓库，更有可能获得更新的变化和修复。

自动化脚本
当然，我们可以每次手动运行该脚本（事实上我可能会制作一个可以组合git clone并运行该脚本的函数），尽管我建议您每次登录 GUI 会话时都运行该脚本。为此，请打开“启动应用程序”菜单，并将脚本（建议使用完整路径和完整文件名）添加为条目。
下次您登录时，您的图标将被设置。
至于手动想法，你可以git clone用操作员一个接一个地运行脚本，或者更好的是，像这样&&创建一个函数：~/.bashrc
$ tree
.
0 directories, 0 files
$ typeset -f my_gitclone
my_gitclone ()
{
git clone "$1" && ~/GIT/sergrep/set_folder_icon.py -e github
}
$ my_gitclone https://github.com/SergKolo/sergrep
