If your data file is very large you would need to drop the slurp (-0777) which would mean that as-is, the filtering wouldn't be as effective. But the principle of first throwing away as much as possible (safetly--replacing with spaces or newlines so that you don't run good data together) is a useful first pass at extracting small pieces from large volumes.
