Thanks again Ken. That's the problem with the ignorant, we just don't know the
importance of each symbol / character in the answer. I didn't want to use the
recommendation as it was because I only wanted to remove the error* files. I
(incorrectly) assumed the slash was marking parameters rather than ensuring the * was
passed as an uninterpreted character. Now I see why either erro\* or "erro*" would
work.
I guess it's time to get educated. Definitely not enough info in the bash man page for
me to become effective with it. Does anyone want to suggest a bash tutorial?
