How to delete scheduled jobs in the organization

• Running this code will delete ALL scheduled jobs in the organization
• You will need to reschedule all jobs manually after running this
• If you are unsure of the impact of this, please contact your internal development team
• If you wish to use ScheduleJob ID  instead of cronTrigger ID to abort the job using System.AbortJob()  use API version 32.0 or below  

List<CronTrigger> listCronTrigger = [select Id, CronExpression, EndTime, NextFireTime, OwnerId,

        PreviousFireTime, StartTime, State, TimesTriggered, TimeZoneSidKey from CronTrigger
        where State = 'Waiting' or State='Running'];
       
System.debug('No of jobs: '+listCronTrigger.size());

If (listCronTrigger.size() > 0)
{
    for (Integer i = 0; i < listCronTrigger.size(); i++)
    {
        System.abortJob(listCronTrigger[i].Id);
        System.debug('Job details ::'+String.valueOf(listCronTrigger[i]));
    }
}
