Keep retrying a bash command until it fails

This week I noticed a test was flaky, and was occasionally failing in CI. So I wanted to re-run my script until it failed.

I had no clue how to do this, so after a bit of trying, I got the following script. This keeps running vendor/bin/phpunit until it fails. You can save it as run.sh and then just run sh ./run.sh in your terminal, and it will keep running.

#!/bin/sh

set -e
while [ true ] do
    vendor/bin/phpunit
done
