sh is a full-fledged subprocess replacement for Python 2, Python 3, PyPy and PyPy3 that allows you to call any program as if it were a function:

from sh import ifconfig
print(ifconfig("eth0"))

sh is not a collection of system commands implemented in Python.

sh relies on various Unix system calls and only works on Unix-like operating systems - Linux, macOS, BSDs etc. Specifically, Windows is not supported.

Testing

I've included a Docker test suite in the docker_test_suit/ folder. To build the image, cd into that directory and run:

$> ./build.sh

This will install ubuntu 18.04 LTS and all supported python versions. Once it's done, stay in that directory and run:

$> ./run.sh

This will mount your local code directory into the container and start the test suite, which will take a long time to run. If you wish to run a single test, you may pass that test to ./run.sh:

$> ./run.sh FunctionalTests.test_unicode_arg

To run a single test for a single environment:

$> ./run.sh -e 3.4 FunctionalTests.test_unicode_arg

Coverage

First run all of the tests:

$> SH_TESTS_RUNNING=1 coverage run --source=sh -m unittest

This will aggregate a .coverage. You may then visualize the report with:

$> coverage report

Or generate visual html files with:

$> coverage html

Which will create ./htmlcov/index.html that you may open in a web browser.
