Usage

You can pass a filename:

Alternatively, it's also possible to pipe from stdin:

$ cat types.txt | topk

For approximate results using the filtered space-saving algorithm, you can pass -approx:

$ topk -approx types.txt

Why

Because my fingers hurt from typing sort | uniq -c | sort -rn | head.
