shebang如何执行程序? [英] How does the shebang execute the program?

问题描述

我觉得自己是个菜鸟，但是我想知道程序( Ex :#!/usr/bin/env python)中的shebang是如何执行的?

I feel like a total noob asking this question, but I'm wondering, how does the shebang in a program (Ex: #!/usr/bin/env python) execute it?

我知道该文件是由./filename运行的，但是如何使用正确的执行程序来运行它呢?

I know that the file is run by ./filename, but how does it run it with the right executor?

与使用python命令运行它是否相同?如果是这样，shebang如何将其重定向到命令?

Would it be the same as running it with the python command? If so, how does the shebang redirect it to the command?
