You have different way to solve your problem. If you need a quick one, you need to know that any shell entry can be used through python subprocess:

from subprocess import call
call(["ls", "-l"])

But if you have time, and you want to power the python API, you should give a look to the OS and SYS libraries:

https://docs.python.org/2/library/os.html https://docs.python.org/2/library/sys.html

Anything written with these lib should be usable from Unix or windows.

And to replicate the behaviour or more fancy command, like tail , you will need to look a bit around. For example this question provide several suggestions: How to implement a pythonic equivalent of tail -F?

Like using the library tailf .
