+
+This script will iterate over all the projects, and check whether a job has Build periodically trigger enabled.
+If the project type is Freestyle job the Build periodically trigger will be disabled.
+Otherwise, it prints the name of the project without modifying the trigger settings.
+For a pipeline project, i.e. org.jenkinsci.plugins.workflow.job.WorkflowJob, you may want to modify
+the Jenkins file that contains `triggers { cron(H/4 * * * *) }` instructions.
