英文:
Goalng exec.Command with exiftool creates extra file named {filename}_original when setting tags
问题
我正在尝试使用golang更新图像元数据。我找到的最简单的方法是使用os/exec运行exiftool，但由于某种原因，这还会创建一个包含原始标签的文件，文件名为原始文件名加上"_original"。
简化的代码如下：
func main() {
cmd := exec.Command("exiftool", "-ImageDescription=\"this should work???\"", "image.png")
err := cmd.Run()
if err != nil {
log.Fatal(err)
}
}
这段代码确实按预期设置了标签，但会创建一个额外的文件，文件名为"image.png_original"。据我所知，这没有任何理由发生。我已经查看了os/exec和exiftool的文档，但没有找到任何相关信息。
虽然我可以删除额外的文件，但这样做很麻烦，我相信一定有更好的方法，只是我还没有找到。
感谢任何帮助

I'm attempting to update image metadata using golang. The simplest way I've found to do this is simply running exiftool with os/exec, but for some reason this also creates a file that contains the original tags, called whatever the original file is called, plus "_original".
Simplified code is as follows:
func main() {
cmd := exec.Command("exiftool", "-ImageDescription=\"this should work???\"", "image.png")
err := cmd.Run()
if err != nil {
log.Fatal(err)
}
}
It does set the tags as expected, but creates an extra file called "image.png_original". As far as I can tell this has no reason to happen. I've checked documentation for os/exec as well as exiftool and haven't found anything.
While I could just delete the extra file, that's messy and I'm sure there's a better way that I just haven't been able to figure out.
Any help is appreciated

根据exiftool文档所说，你可以使用选项"-delete_original"。根据你的具体用例，你也可以考虑使用"-overwrite_original"选项。你可以阅读文档获取更多信息。

As the exiftool documentation says, you can use the option "-delete_original" . You can consider "-overwrite_original" option as well, depending on your exact use case. You can read the docs for more information
