Count words in plain text file

word-statistics.sh

# This snippet can be used on the command line (tested on a Mac) to get a quick list of word frequencies in the file FILENAME.
# Counting will be done case-insensivitely, i.e., differently cased words will be counted together.
# The result will be written in the file stats.csv (or any other that you give at the end) in the form of a space-separated table
cat FILENAME |  tr '[[:punct:][:space:]]' '\n' | sort | uniq -ci | sort -nr | tail -n +2 > stats.csv
