words of encouragement - TY!! I am in advanced age as well - so it should work (experience is on our side
as for my original question: I have been able to get the data from multiple sensors, using a recursive function, and put data into a MySQL database/ table. Then I started doing some research on how to access this information with something GUI such as LibreOffice spreadsheet. Did not go so well.
But, during the research found an example of batch commands cat in conjunction with grep, and, wow, have not been able to use past experience to echo the info into a .cvs file.
So, am doing a little more with bash as well as, when time permits, some research on MySQL and SQLlite.
Hope this thread will continue with ideas as it is an interesting bash vs SQL topic at this point.
