Runs latexmk in draft mode (fastest) followed by a batch mode (actually generate the PDF).

latexmk-fast

#!/bin/bash

## Simple draft mode followed by pdflatex once by using the print hook.
## With no arguments, it will follow a 'latexmkrc' file if there is one.
## You still get the nice error messages at the end:
latexmk -pdf -pdflatex='pdflatex -draftmode %O %S && touch %D' -print=pdf -e '$lpr_pdf=q|pdflatex -interaction=batchmode -synctex=1 %R|' "$@"
