I have a cron job that is scheduled to run everyday, other than changing the schedule, is there any other way to do a test run of the command right now to see if it works as intended?  
how can I make cron run a job right now, for testing/debugging? without changing the schedule!
cron;debugging
As far as i know there is no way to directly do that as cron has a special purpose - running schedules commands at a specific time. So the best thing is to either to  manually create a crontab entry or write a script which removes and resets the environment.
