The Code

Of course, the thing to do is to wrap this procedure into a tidy script. Copy the following Bourne shell script into a file named make_index.sh, and make it executable by applying chmod 700. Windows users can get a Bourne shell by installing MSYS .

#!/bin/sh

# make_index.sh, version 1.0

# usage: make_index.sh

# requires: pdftk, kw_catcher, page_refs,

# pdftotext, enscript, ps2pdf
