I got excited when I saw the 'f' and 'count' commands, but they're just scripts he has on his system. Like doing grep 'plover' blah.log | cut -d ' ' -f 11 | sort | uniq -c | sort -n. Personally I'd prefer to use the ubiquitous commands that work everywhere than rely on having custom scripts on my system, but they are nice.
