How can I find count of every word in a file?
I want a histogram of each word in text pipe or document.
I was already able to split up document into a list of words; so each word is on a new line. If you can get it working directly from text document then a solution from there is fine too.
> cat doc.txt word second third word really > cat doc.txt | ... # then count occurrences of each word \ and print in descending order separated by delimiter word 2 really 1 second 1 third 1
It needs to be somewhat efficient as file is 1GB text and cannot work with exponential time load.
