If I might take some of the mystery of using cron. In UNIX, typing crontab -e will enable you to put your entry into a "scheduler".

     Each  line  in  a  crontab  file  consists  of  six  fields,
     separated by spaces or tabs, as follows:

          minutes   hours     day-of-month   month     day-of-
          week    command
 
     minutes        Minutes field, which can have values  in  the
                    range 0 through 59.

     hours          Hours field, which can  have  values  in  the
                    range 0 through 23.

     day-of-month   Day of the month, in the range 1 through 31.
 
     month          Month of the year, in the range 1 through 12.
 
     day-of-week    Day of the week, in the range  0  through  6.
                    Sunday  is  day  0  in this scheme of things.
                    For backward compatibility  with  older  sys-
                    tems, Sunday may also be specified as day 7.

     command        Command to be run.  A  percent  character  in
                    this   field   (unless   escaped   by  \)  is
                    translated to a NEWLINE character.  Only  the
                    first  line (up to a % or end of line) of the
                    command field is executed by the Shell.   The
                    other lines are made available to the command
                    as standard input.
