Damn.. and I just write a code to convert CBR/CBZ/ZIP/RAR comics to PDF

I can even batch mode on them with:

ls | while read comic; do cb2pdf "$comic"; done

here goes the code

#!/bin/bash

	else
		EXTENSION="$( echo ${SOURCE##*.} | tr [:upper:] [:lower:] )"
		[ -n "$DEBUG" ] && echo "Extension --$EXTENSION--"
		case $EXTENSION in
			cbr|rar) SOURCETYPE="rar" ;;
			cbz|zip) SOURCETYPE="zip" ;;
		esac
	fi
	[ -n "$DEBUG" ] && echo Source detected "$SOURCETYPE"
}
