Also, I'd like to put in some error handling. Specifically to watch for file names that would not be present. Would I be looking for the program code variable "$?"? I'm seeing from other examples that checking $? for a non-zero value indicates that the command failed.
The for loop loops through the number of items, separated by spaces, in the variable.
There are more ways to read a file but the used methode is preferred.

Use the test statement for the existence of a file with the -a option.
