Psmith, the TeX bot, in fixed font mode: Here's the output from texdef:

\tilde:
macro:->\mathaccent "707E\relax

Just checking if this ok question to ask on main board. I can;t figure how to do this. I need more levels inserted/added above the \chapter level . I do not know how to do it. Like this

\documentclass[]{book}
\begin{document}
\part(part ONE}
 ....
 \subpart{sub part}
   ....
   \subsubpart{....}
     ...
     \chapter{....} % NO CHANGE NEEDED BELOW THIS LEVEL
       \section{...}
         \subsection{....}
     \chapter{...}

\end{docuemnt}

#!/bin/bash

if [ "$#" -ne 1 ]; then
  echo "I need a PDF!"
  exit 1
fi

pages=`pdfinfo "$1" | grep Pages | sed 's/[^0-9]*//'`
filename="${1%.*}"

if [ $((pages % 2)) != 0 ]; then
    echo "Run, run, run! The PDF has an odd number of pages!"
    exit 1
fi

for (( i = 1 ; i < $pages ; i=i+2 ))
do
    echo "Duck."
    pdftk A="$1" cat A$i-$((i+1)) output "$filename-$i-$((i+1)).pdf"
done
echo "Goose."
