Hi, is there simple solution for making scheduler run only on work days Monday through Friday? every week in ya year 
, is there similar option like in crontab.
If not there is a little feature that could be integrated.
You will probably need to incorporate this script into yours at the start. Run the script every day, but exit on the weekend before any other part of the script executes.
