# retry.sh retries a command until it succeeds. It accepts a regex pattern to match failures on to
# determine if a retry should be attempted.
# Example: retry.sh "connection timed out" ./my-flaky-script.sh some args
# This will run "my-flaky-script.sh", retrying any failed runs that output "connection timed out" up
