Perl Programming quiz, level Advanced, question 11
Question: If you are opening a file for read access, and you know that others may open it at the same time, possibly to modify its contents, you should:
Answer 1:Open it with a non-exclusive lock
This was the CORRECT answer
Answer 2:Open it with a non-blocking lock
Answer 3:Use seek prior to each read
Answer 4:Take no special action - that's only necessary if you were opening the file to modify it yourself

This was a question from our quiz ... but we have now provided you with the answer (above) - we prefer to provide you with information rather than to puzzle you.
