Requires texcount, generates wordcount, charcount without spaces, charcount with spaces and pagecount based on charcount w/spaces (2400/page). Count characters in latex. Count words in latex.

charcount.sh

#!/bin/bash

wordcount=$(texcount Main.tex | sed -n 3p | sed 's/[^0-9]*//g')
charcount=$(texcount -char Main.tex | sed -n 3p | sed 's/[^0-9]*//g')
charcountws=$(($charcount + $wordcount))
pages=$(echo "$charcountws 2400" | awk '{printf "%.2f", $1/$2}')

echo 'Wordcount:' $wordcount
echo 'Charcount no spaces:' $charcount
echo 'Charcount w/spaces:' $charcountws
echo 'Pagecount based on charcount:' $pages
