usmo 0.8.0

Bootstrap machines and run cached utility scripts from one CLI.

usm

usm is a lightweight CLI for machine bootstrap tasks and day-to-day utility scripts. It gives you one command for common setup jobs, Azure/blobfuse workflows, and a few personal productivity helpers, while keeping the underlying scripts easy to iterate on.

The package installs as usmo, but the executable command is usm.

Highlights

• One entrypoint for machine setup, storage helpers, and quick admin tasks.
• On-demand script download and caching under ~/.cache/usm/scripts.
• Python subcommands run with the package interpreter, which keeps uv tool installs isolated and reliable.
• Local --debug mode for iterating on scripts in this repository without downloading from GitHub.
• Simple release flow driven by Git tags.

Installation

Quick Install (recommended)

curl -fsSL https://raw.githubusercontent.com/HSPK/usm/main/scripts/install.sh | bash

The script will automatically install uv (via the official installer at https://astral.sh/uv) if needed, then install usmo via uv tool install. You may need to run source ~/.bashrc (or restart your shell) afterwards for the usm command to become available.

Manual Install

Install uv first, then install usmo as a uv-managed tool:

uv tool install usmo
# upgrade later with:
uv tool install --upgrade usmo

PyPI package page: https://pypi.org/project/usmo/

Or install from a local checkout while developing:

uv sync
uv tool install --force .

After installation, the CLI is available as:

usm <command> [args...]

Commands

usm bundles machine-setup scripts, networking/proxy tools, file servers, and a few built-in helpers. Scripts live in scripts/_config.json and download on first use — add new ones by editing that file, no Python changes required.

See everything (with one-line descriptions and cache status) from the CLI:

usm list                 # all commands
usm <command> --help     # help for one command

Aliases

Install any script as a short command on your PATH:

usm install clash cx     # `cx ...` now runs `usm clash ...`
usm uninstall cx

Shims are written to ~/.local/bin; usm warns if that directory isn't on your PATH.

Updating

usm update               # refresh the catalog (_config.json) only
usm update --all         # re-download every cached script
usm update tunnel        # refresh a single script

Examples

usm init                                        # bootstrap a machine
usm blobmount /mnt/data myaccount mycontainer   # mount an Azure blob container
usm cp /mnt/data/project ./backup               # azcopy-backed when Azure is involved
usm --upgrade check_py                          # force-refresh a script before running
usm --debug check_py                            # run from local ./scripts (no download)

See usm <command> --help or the docs for per-command usage.

How it Works

The CLI keeps a small manifest of commands in src/usmo/cli.py.

• Shell scripts are executed with bash.
• Python scripts are executed with the current interpreter via sys.executable.
• Remote scripts are downloaded from this repository and cached locally.
• --upgrade forces a fresh download of the selected script.
• --debug bypasses the cache and runs the local file under scripts/.
• Managed alias insertion uses start/end markers so rerunning the command updates the block instead of duplicating it.
• inject-alias is implemented with click and supports bash, zsh, and PowerShell profile targets.

Development

Install the project locally:

uv sync

Build distributable artifacts:

uv build

Smoke-test the installed command:

uv run usm check_py

Release Flow

This repository includes a GitHub Actions workflow at .github/workflows/release.yml.

When you push a tag like v0.1.9, GitHub Actions will:

1. Build the source distribution and wheel with uv build (version is derived from the git tag automatically via hatch-vcs).
2. Create or update a GitHub Release for that tag.
3. Upload the built artifacts to the release page.
4. Publish to PyPI via Trusted Publishing (no secrets needed).

Create a new release with:

git tag -a v0.1.9 -m "v0.1.9"
git push origin v0.1.9

Notes

• Some scripts are tailored for Ubuntu-based environments.
• blobmount and cp expect Azure CLI / azcopy / blobfuse2 style workflows.
• Cached scripts live in ~/.cache/usm/scripts.
