The crontab entries are different on a NeXT...  The above is wrong for
NeXT 2.0...

pasc

From the cron(8) man page
     The crontab files consist of lines of seven fields each.
     The fields are separated by spaces or tabs.  The first five
     are integer patterns to specify:

     + minute (0-59)
     + hour (0-23)
     + day of the month (1-31)
     + month of the year (1-12)
     + day of the week (1-7 with 1 = Monday)
             
     Each of these patterns may contain:
             
     + a number in the range above
     + two numbers separated by a minus meaning a range inclusive
     + a list of numbers separated by commas meaning any of the
       numbers
     + an asterisk meaning all legal values
             
     The sixth field is a user name: the command will be run with
     that user's uid and permissions.  The seventh field consists
     of all the text on a line following the sixth field, includ-
     ing spaces and tabs; this text is treated as a command which
     is executed by the Shell at the specified times.  A percent
     character (``%'') in this field is translated to a new-line
     character.
