   I cribbed this script together with help to run every three days when    
   NOAA updates their space weather forecast.  The daily cron job runs this at   
   0900 ET:   
      
   ===   
   #!/bin/bash   
      
   # The following is from:   
   #    
   https://askubuntu.com/questions/829408/execute-bash-script-literally-after-ever   
   y-3-days   
   # This is to account for actually running every three days   
   # correctly since cron can't do it.   
      
   # Minimum delay between two script executions, in seconds.    
   seconds=$((60*60*24*3))   
      
   # Compare the difference between this script's modification time stamp    
   # and the current date with the given minimum delay in seconds.    
   # Exit with error code 1 if the minimum delay is not exceeded yet.   
   if test "$(($(date "+%s")-$(date -r "$0" "+%s")))" -lt "$seconds" ; then   
       echo "This script may not yet be started again."   
       exit 1   
   fi   
      
   # Store the current date as modification time stamp of this script file   
   touch -m -- "$0"   
      
   # Insert your normal script here:   
   MBSE_ROOT=/opt/mbse;export MBSE_ROOT   
   cd $MBSE_ROOT/temp   
   lynx -dump "https://services.swpc.noaa.gov/text/3-day-forecast.txt" > forecast   
   $MBSE_ROOT/bin/mbmsg post All 155 "3-Day Space Weather Forecast" ./forecast -    
   -quiet   
   ### Kill off the text file   
   rm -f ./forecast   
   ===   
      
   I haven't tried using this script under sh yet.   
      
   This might be helpful.
