I need to schedule a process/program every hour on the hour between 9am and 4pm on the 2nd through the 9th of each month except on Saturday and Sunday. So, I tried this entry: 0 9-16 2-9 * 1-5 ./myprog.sh Unfortunately it runs outside of the 2nd through the 9th and still runs on Sat. through Sun. Is there a way to do this (outside the program itself)? -Frank
