如果徽标包含特定文件/子目录，请将徽标放在文件夹图标上
如何为所有目录创建脚本和系统规则，如果文件夹包含.git直接子文件夹，它将在每个目录的图标上应用标志？ 我已经在这样的标志中加入了github标志图标
输出效果应如下：

下面提供的脚本允许设置github存储库图标或标志（但不是两者），以及将元数据重置为默认值。 使用非常简单，如-h选项所述：
$ ./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 .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所有github存储库的主文件夹并设置它们的标志，我们将执行set_folder_icon.py -e myemblemname -r $HOME或只是cd; set_folder_icon.py -e myemblemname cd; set_folder_icon.py -e myemblemname
为了获得最佳性能，请创建~/bin目录并将脚本存储为set_folder_icon.py 。 如果要立即使用它，请运行source ~/.bashrc 。 如果您使用的是其他shell，请确保将~/bin添加到$PATH变量中。
注意 ：脚本可以使用--icon选项获取任意文件，但是--emblem要求您将特定文件存储在~/.local/share/icons ，文件名类似于emblem-github 。 有关示例，请参阅“操作中的脚本”部分
脚本在行动
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存储库如何将其徽标设置为自定义徽标。

脚本
该脚本也可以在我的个人GitHub存储库中使用 ，它更有可能获得更新的更改和修复。

自动化脚本
当然，我们每次都可以手动运行脚本（实际上我可能会创建一个可以组合git clone并运行此脚本的函数），尽管我建议您每次登录GUI会话时都运行脚本。 为此，请打开“启动应用程序”菜单，然后添加脚本（建议使用完整路径和完整文件名）作为条目。
下次登录时，您的图标将被设置。
至于手动的想法，你可以用&&运算符一个接一个地运行git clone和脚本，或者更好的是在~/.bashrc为它做一个函数，如下所示：
$ 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 Cloning into 'sergrep'... remote: Counting objects: 387, done. remote: Compressing objects: 100% (17/17), done. remote: Total 387 (delta 10), reused 17 (delta 5), pack-reused 365 Receiving objects: 100% (387/387), 115.65 KiB | 0 bytes/s, done.
