Clean rundeck executions logs older than a given amount of days but keep a minimum amount of executions per job.
#!/bin/bash
# This script will clean executions older than a given amount of days ($DAYS) but will keep at least $KEEP executions.
# Based on @unicolet gist that keeps last 30 exec of each job ( https://gist.github.com/unicolet/af648a97163ce6b44645 )
# Taken from @lucabusin the workflow tables cleaning code ( https://gist.github.com/lucabusin/cad36a45764f2fc2e2daa81e2db4186d )
# setup ~/.mycnf or ~/.pgpass to allow passwordless connection to mysql/postgres
# Comment / Uncomment below to use postgres or mysql.
# Days to keep executions.
DAYS=90
# Minimum Amount to Keep

A step-by-step guide how to use Python with Tor and Privoxy

Tested on Ubuntu 18.04 Docker container. The Dockerfile is a single line FROM ubuntu:18.04. Alternatively, you can simply run docker run -it ubuntu:18.04 bash.

NOTE: stopping services didn't work for me for some reason. That's why there is kill $(pidof <service name>) after each failed service <service name> stop to kill it.
