How can I find count of every word in a file?
I want a histogram of each word in text pipe or document. New line and empty lines will exist in document. I stripped everything except for
> 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.
