Ever wanted a simple way to repeat a particular command at a particular cadence? spam runs any command you'd like at a set rate.
This is mainly intended for scenarios where you'd like to generate synthetic traffic via curl, but can also work with any other program of your choosing.
Usage
spam [-r RATE_PER_SECOND] -- PROGRAM_ARGS
Examples
Send 10 req/s to www.google.com
spam -r 10 -- curl www.google.com
Send 1 req/s to localhost:8080
spam -- curl localhost:8080
Add a 10 "hello" lines to a particular file per second
spam -r 10 -- bash -c 'echo "hello" >> ./text.txt'Installation
Mac OS
You can use brew tap to install:
brew tap Steven-Ireland/homebrew-tap brew install spam
Linux
Head over to Releases and download the latest release binary. You'll need to place it on your PATH manually.

This program outputs durations in milliseconds for each run -- you can pipe the output to asciigraph for a nice visual moving representation:
spam -r 10 -- curl www.google.com | asciigraph -r -h 10 -w 40
Questions / Contributions
Feel free to open an issue or submit a PR if anything comes up. It's a pretty tiny program at the moment, so larger features may be left open to community contributions.
