Un amico mi chiese una applicazione per poter cercare nei pdf….. 2 soluzioni

a) recoll http://www.lesbonscomptes.com/recoll/download.html#general

b) pdfgrep https://gitlab.com/pdfgrep/pdfgrep

presenti sia sotto linux che sotto windows.

Lo script per estrarre pagine pdf da un file pdf piu’ grande il file si chiama pdfselect.sh

#!/bin/bash
# extract pages from a big pdf file using gs
# Usage:
#           pdfselect.sh pdffile startPageNumber endPageNumber

function getPDFPages()
{
if [ -e $1 ]; then
pdfinfo $1 | grep “Pages“ | awk ‘{print $2}‘
else
echo 0;
fi
}

if [ $# -lt 2 ]; then
sed -n ‘3,4p‘ `which pdfselect.sh`
exit
fi

oriPdf=$1
[ ! -e ${oriPdf} ] && echo “${oriPdf} does not exist! “ && exit

numPage=`getPDFPages ${oriPdf}`
[ ${numPage} -eq 0 ] && “ZERO page is found in ${oriPdf}“ && exit

sPage=$2
[ ${sPage} -gt ${numPage} ] && ${sPage}=${numPage}
