Issue
Suppose I have a python script called a.py like this:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# Author : Bhishan Poudel
# Date : Jul 13, 2016
# Imports
# Script
print("hello")
I can run this scripts in two ways:
Using python interpreter:
python3 a.py
Changing permission
chmod a+x a.py; ./a.py
QUESTION
How can I run any new or old python scripts without using chmod a+x script_name all the times.
I have root access and user access both to my computer.
Basically i want executable permission to all the .py files, how can we do so?
I tried different shebangs such as:
#!/usr/bin/python3
#!/usr/bin/env python3
#!/usr/local/bin/python3
#!/usr/local/bin/env python3
The python interpreter is also in the $PATH. The output of echo $PATH is following:
/Library/Frameworks/Python.framework/Versions/2.7/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/texbin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/opt/local/bin:/Users/poudel/phosim:/Users/poudel/Applications:/usr/local/octave/3.8.0/bin:/Users/poudel/Applications/Geany.app/Contents/MacOS/:/opt/local/bin:/Users/poudel/phosim:/Users/poudel/Applications:/usr/local/octave/3.8.0/bin:/Applications/Geany.app/Contents/MacOS/:/opt/local/bin:/Users/poudel/phosim:/Users/poudel/Applications:/usr/local/octave/3.8.0/bin:/Applications/Geany.app/Contents/MacOS/
Also, ls /usr/bin/py* has:
/usr/bin/pydoc* /usr/bin/python2.5@ /usr/bin/pythonw*
/usr/bin/pydoc2.5@ /usr/bin/python2.5-config@ /usr/bin/pythonw2.5@
/usr/bin/pydoc2.6@ /usr/bin/python2.6@ /usr/bin/pythonw2.6@
/usr/bin/pydoc2.7@ /usr/bin/python2.6-config@ /usr/bin/pythonw2.7@
/usr/bin/python* /usr/bin/python2.7@
/usr/bin/python-config* /usr/bin/python2.7-config@

Permission denied when launch python script via bash
Solution
The hard way
Run below with root privilege:
find /your/path/ -type f -name "*.py" -exec chmod u+x {} \;
Note:
chmod need not be run as root if you're the owner of .py file.
The smart way
Write a script to take care of this.
#!/bin/bash
if [ -f "$1" ]
then
geany "$1" # You could also use xdg-open if you set geany to open .py files
else
cp /path/to/python/startup/template "$1" # You may omit this if you don't have a default template
chmod u+x "$1"
geany "$1"
fi
Save the script as, say, pycreator in say /usr/bin/ , then do
chown root:root /usr/bin/pycreator
chmod +x-w /usr/bin/pycreator
To create a new script using pycreator, do
pycreator calculator.py
