Run bash command in Cygwin from another application

Question

From a windows application written on C++ or python, how can I execute arbitrary shell commands?

My installation of Cygwin is normally launched from the following bat file:

@echo off

C:
chdir C:\cygwin\bin

bash --login -i

Answer 1

From Python, run bash with os.system, os.popen or subprocess and pass the appropriate command-line arguments.

os.system(r'C:\cygwin\bin\bash --login -c "some bash commands"')
