clean up disabled github workflows

workflow_clean.sh

#!/bin/bash
OWNER=<org_name>
REPO=$1
WORKFLOW_NAME=$2

# list workflows
WORKFLOW_IDS=($(gh api -X GET /repos/$OWNER/$REPO/actions/workflows | jq -r '.workflows[] | select(.state=="disabled_manually") | .id'))

for WORKFLOW_ID in "${WORKFLOW_IDS}"
do
	# delete all runs
	echo "deleting existing runs: $WORKFLOW_ID"
	gh api -X GET "/repos/$OWNER/$REPO/actions/workflows/$WORKFLOW_ID/runs" | jq '.workflow_runs[] | .id' | xargs -I{} gh api -X DELETE /repos/$OWNER/$REPO/actions/runs/{}
done

GitHub lacks a way to delete workflows (per https://github.community/t/is-there-a-way-to-delete-or-hide-old-renamed-workflows/16281), this is a dead-simple shell script to delete manually disabled workflows, by removing runs tied to a given repo.

Usage:

chmod +x ./workflow_clean.sh
./workflow_clean.sh your_reponame
