Use case: You've got a multi-GB log file for a whole week, and you need to search for something which happened on Saturday using for example grep. Making an educated guess, you assume that starting the search from the middle of the file will more than halve the processing time (since it's definitely not going to have to process the whole of the rest of the file) while not skipping any relevant data. Is this possible?
