[SeeknFind] word indexing & counting

[fpjm]

Does anyone know about a small utility which would read through a  .txt
file, index and count the words, and present the results sorted, like

word      occurences in that .txt
apple       235
pear        222
strawberry  199   etc...


I found utilities counting the number of words in a text, or the line
numbers, but this is not what I am looking for. Are they sites dealing
with these kinds of tools?

TIA
