Hi,

I’m developping a module for linux with several functions.  
Most of the functions i develop need to launch binary executables.  
I know, the best practice is to use module.run\_command() function to launch commands. But i instantiate the module object in the main() function. So, the module object cannot be used in the functions i develop.

What should i do :

- Pass the module as a variable to myfunctions (myfunctions(module)) ?
- Instantiate another AnsibleModule object in each function ?
- Use os.subprocess() function or equivalent in my functions ?

Why using os.subprocess() is not recommended ?

### begin - code example

myfunction1(module)  
return module.run\_command(“/usr/bin/ip route show”)[1]

def main():  
module = AnsibleModule(argument\_spec = dict())  
result = dict()  
result[‘routes’] = myfunction1(module)

return module.exit\_json(\*\*result)

### end - code example

Have a nice weekend.  
Gabriel.

The typical pattern is to pass the AnsibleModule instance to your functions.
