Well, now that you mention it, that was my flawed logic. I did get rid 
of two places.sqlite files which contained that string, but the message 
continued to appear. The man page I have in bash for grep, references 
the use of regular expressions, and even demonstrates their usage 
briefly, but they didn't include enough detail on the syntax for me to 
get it right.

With all of the exploring I've done in my file system the past few days 
I've discovered that most of the lock files contain a five digit process 
id number, and nothing else, so I suppose I could alter the pattern to 
be matched to a five digits in [] which man grep shows as the way to 
find sets of strings or numbers of a given length.

I've just reread the grep manual, and it has become clear to me that the 
brackets only specify groups, or ranges of characters or numbers, from 
which to make possible matches, and does not specify how many in a row 
you wish to match. I also see glob mentioned, and will spend some time 
in man glob to figure out how to use it.

Thanks for your help. Later, Ray Parrish
