Would't it be great if instead of saying 'failed(1)' we could have a message saying 'unable to write to output file - file locked'. Especially since newbies are not generally able to read and remember all the details in the references, even though these may be obvious to old hands. Gosh, even I did not see that line in the instructions, even though it is clearly there. Perception is a fuzzy thing when beginning a new subject.
