31 How to convert djvu files to pdf?

Install sudo apt-get install djvulibre-bin. To convert multiple files, I wrote this small script

#!/bin/bash 
#dj2pdf.sh    script to convert djvu files to pdf 
set -x 
for file in $1; do 
    filename=${file%.*} 
    ddjvu -format=pdf -quality=100 "$filename.djvu" "$filename.pdf" 
done
 

To convert one file, type dj2pdf  file.djvu and to convert multiple files, type dj2pdf  "*.djvu"
