linux bash script; pick out unusual words; and rank them

#!/bin/bash

# check
#
# pdftotext ain't seem to work in batch
# so do that separately before this.
# We take it from Step 2
# Use spell to write out unusual English words
# Extract any word that starts capitalized
# Count those, sort, list the top 15
#
# Enter the text file as argument
# Usage: ./<check> '081618 Toscas Transcript_Redacted.txt'
