Convert a tex file to an ebook for Kindle

texToKindle.sh

#!/bin/bash

# This script converts a tex source to azw3 format using htlatex and ebook-convert (from calibre)
# to set the resolution of math images edit this file
# sudo gedit /usr/share/texmf/tex4ht/tex4ht.env  
# in the section <dvipng> modify the DPI parameter (-D) of the two commands (I use 100)  

# do the operation in a temporary directory. htlatex produces a lot of files (and we can't set an output dir)
currdir=`pwd`

format="azw3"

cp . "../temp_htlatex" -r
cd "../temp_htlatex"

#now we can convert latex to html
htlatex $1
#html to ebook
ebook-convert "${1%.tex}.html" "${1%.tex}.$format" --language en
#copy the ebook file in the original directory
cp "${1%.tex}.$format" "$currdir/${1%.tex}.$format"
#finally, delete all temp files
cd "$currdir"
rm -rf "../temp_htlatex"
