Execute shell script on cygwin from Python

Question

I want to execute a shell script, on cygwin from Python. The shell script is creating a file as an output.

I tried

import os
import subprocess

os.chdir(r"C:\\cygwin64\\bin\\ ")
cmd = ["bash", "-c", 'cd /<path for the script>; ./test.sh']
subprocess.call(cmd)

os.chdir(r"C:\\cygwin64\\bin\\ ") contains a space. What is your error? — Jean-François Fabre

it gives error as grep command not found, i am using grep in the first line of the shell script — Michael

Have you solved this issue? I have a script and some commands work and some others like "cp", "sed" doesn't — euge1780

This works:

import os, subprocess
os.chdir(r"C:\cygwin64\bin")
cmd = ["bash", "-c", "cd $HOME; pwd; exit"]
ret = subprocess.call(cmd)

I have tried with a script that includes commands like cp or sed and it doesn't work. But there are other commands in the same script, like test, do, for, echo and works fine. Any idea?
