[PYTHON] Create an executable file in a scripting language

Write the line starting with #! On the first line of the file as shown below.

hoge.rb


#!/usr/bin/env ruby

(Program contents)

#! Is a shebang, a command written below it that will re-execute itself. By using / usr / bin / env, you don't have to write the environment-dependent PATH that appears in which ruby. / usr / bin / env is also environment-dependent, but it is almost common, and if you can execute env with this PATH even if it is not included by default, it will be a problem after that I think it's okay because it doesn't exist.

After that

$ chmod +x hoge.rb

If you give execute permission,

$ ./hoge.rb

Can be executed like.

In other languages, you can replace the ruby part with perl, python, etc.

hoge.py


#!/usr/bin/env python

Supplement

Used to specify the character code,

# coding: utf-8

Etc. are brought to the second line, so it's OK.
