Utilities for setting up and running experiments remotely


Latest version Documentation

Utilities for setting up and running experiments remotely.

This is kind of a "living repo". I will add to it utilities as I find them useful (or people submit PRs).

It is heavily inspired by spur.py but it also contains a bunch of utility routines that I have found useful.


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


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

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 docs. Feel free to open an issue on the repo if anything is unclear.
