问题描述
我有一个基于 Python 的 GTK 应用程序，可以加载多个模块.它从 (linux) 终端运行，如下所示:
I have a python-based GTK application that loads several modules. It is run from the (linux) terminal like so:
./myscript.py --some-flag 设置
用户可以从程序中下载(使用 Git)更新的版本.如果存在/已下载，则会出现一个按钮，我希望使用新编译的内容(包括依赖项/导入)重新启动程序.最好它还使用 sys.argv 的内容重新启动它，以保持所有标志原样.
From within the program the user can download (using Git) newer versions.If such exists/are downloaded, a button appear that I wish would restart the program with newly compiled contents (including dependencies/imports). Preferably it would also restart it using the contents of sys.argv to keep all the flags as they were.
所以我没有找到/需要的是一个很好的重启过程，它会杀死程序的当前实例并使用相同的参数启动一个新的实例.
So what I fail to find/need is a nice restart procedure that kills the current instance of the program and starts a new using the same arguments.
最好该解决方案也适用于 Windows 和 Mac，但这不是必需的.
Preferably the solution should work for Windows and Mac as well but it is not essential.
推荐答案
您正在寻找 os.exec*() 命令族.
You're looking for os.exec*() family of commands.
要使用与最初运行时完全相同的命令行参数重新启动当前程序，您可以使用以下命令:
To restart your current program with exact the same command line arguments as it was originally run, you could use the following:
os.execv(sys.argv[0], sys.argv)
