Hi Chris,

I read your article @ https://chrisdown.name/2015/09/27/auto-merging-successful-builds-from-travis-ci.html

I sugget you to edit the script to include the GITHUB_SECRET_TOKEN also during the cloning to allow the scripts to work also on private repositories.

line 17 should be git clone "https://[email protected]/$GITHUB_REPO" "$repo_temp”

Cheers,
Michele

Only one problem with that: that will display the secret in the output, so it would require the cloning to also be redirected to /dev/null to avoid leakage.
