Utilities for setting up and running experiments remotely.

spurs is heavily inspired by spur.py but it also contains a bunch of utility routines that I have found useful. I will periodically add more as I find useful ones or people submit PRs.


This repo contains two crates:

  1. spurs: A straight-forward, well-typed, idiomatic interface for running commands remotely via SSH, similar to spur.py.

  2. spurs-util: Utilities for common Linux admin operations, such as adding a user to a group or turning on a swap device or installing a package. This is by no means a complete set of such functions. So far it just includes the ones I have run into. Feel free to make PRs adding more.


While I do intend to follow semver for the API, I don't not make guarantees about the format of output to stdout or stderr. It is not intended that one should try to parse the stdout/stderr output generated by spurs.


use spurs::{cmd, ssh::{SshShell, Execute}};

const FOO: &str = "foo";
const HOST: &str = "";
const USER: &str = "user";

// Create an SSH connection with host.
// (host doesn't have to be a `&str`; it can be any `ToSocketAddrs` type)
let shell = SshShell::with_default_key(USER, HOST)?;

// Run some commands on HOST as USER.

// ps -e | grep foo
shell.run(cmd!("ps -e | grep {}", FOO).use_bash())?;

// cd /home/user ; ls -a | grep user
shell.run(cmd!("ls -a | grep user").cwd("/home/user/").use_bash())?;

// sudo yum install -y qemu-kvm

It's also possible to

  • run commands in another thread and later wait for that thread
  • capture the stdout and stderr
  • allow a command to fail

For more information please see the spurs docs or the spurs-util docs. Feel free to open an issue on the repo if anything is unclear.


Add the crate spurs to your Cargo.toml dependencies.

Requires stable Rust 1.32 or newer.
