-bash: ./manage.py: Permission denied
Solution 1:
You need to make manage.py executable to excecute it. Do chmod +x manage.py to make it excecutable. Alternately you can do python manage.py <cmd> instead.
Solution 2:
To give yourself execute permission for the file containing the script use the command:
chmod u+rwx filename.py
To give other users permission to read and execute but not alter the shell script use:
chmod go+rx filename.py
