如何使Shell脚本启动python脚本？

Question

I need a .command file that can launch a python script in the same directory as it.

I have so far gotten this:

#!bin/bash
python /Users/username/Desktop/IF.py

But every time the Terminal returns the same error.

Answer 1

Why not just launch the python script itself from the get-go? You can add a shebang at the top like so:

#! /user/bin/env python
... the rest of your python script here

Then just give the script executable permissions:

chmod +x nameofscript.py

Then just launch it like so:

./nameofscript.py

In case you don't want the script to rely on the environment, just use the following shebang instead:

#! /usr/bin/python

Answer 2

Maybe because the shebang (or hashbang ). About what is shebang (wiki) .

#!bin/bash
  ^ 
python /Users/username/Desktop/IF.py

This means the system will use bin/bash to run this program, but bin/bash means path/bin/bash .

For example, if you're in /home then the system will use /home/bin/bash to run this program.

I think you need this:

#!/bin/bash
python /Users/username/Desktop/IF.py

Note that I replaced #!bin/bash to #!/bin/bash .
