Python：编译成Unix命令行应用程序

Question

I am not sure if I searched for the wrong terms, but I could not find much on this subject. I am on osx and I'd like to compile a commandline python script into a small commandline app, that I can put into usr/local/bin so I can call it from anywhere. Is there a straighforward way to do that?

Thanks

Answer 1

The simplest way to do this is to rename your file from filename.py to filename and add this line to the top of the file.

#!/usr/bin/env python

You may also need to set the executable bit on the file, which may be set using chmod +x on the command line.

Answer 2

On Unix it works usually in the following way:

1. Put #!/usr/bin/env python in the first line of your .py script.
2. Add execution permissions to the file (using chmod ).
3. Execute the script from command line, eg. by providing ./my_script.py when in the same directory.

What else do you need?

Answer 3

A Python script is already a "command line app" that you can put anywhere.

Just set the first line of your script to be a proper shebang pointing to your Python interpreter For example:

#! /usr/bin/python

(Or wherever OS X puts its Python interpreter), set your script with the executble attributes, and put it on your bin folder

(it does not need to end in ".py" either)

Answer 4

you can write

#!/usr/bin/python 

in the very beginning of your script or write shell script that will lauch your script like

#!/bin/sh
python path_to_your_script/your_script.py

Answer 5

As almost everybody said, you can turn your script executable by adding the following line at the beginning of the script:

#!/usr/bin/env python

and setting it to be executable:

chmod +x script.py

Another alternative, is to convert your script into a native executable . For that, you may use Freeze or py2exe , depending on your target platform.
