sh 2.3.0

Python subprocess replacement

sh is a full-fledged subprocess replacement for Python 3.8 - 3.14, and PyPy that allows you to call any program as if it were a function:

from sh import git
print(git("status", "--short"))

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.

Developers

Testing

Tests are run in a docker container against all supported Python versions. To run, make the following target:

$> make test

To run a single test:

$> make test='FunctionalTests.test_background' test_one

Docs

To build the docs, make sure you’ve run poetry install to install the dev dependencies, then:

$> cd docs
$> make html

This will generate the docs in docs/build/html. You can open the index.html file in your browser to view the docs.

Coverage

First run all of the tests:

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

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.
