Question

#!/bin/bash

printf "Content-type: text/html\n\n"

sudo convert /usr/lib/cgi-bin/images/* /usr/lib/cgi-bin/images.pdf

sudo ocrmypdf /usr/lib/cgi-bin/images.pdf /usr/lib/cgi-bin/pdf/images_ocr.pdf

printf "done"

• above script is in cgi-bin folder with 755 permission
• in browser http://localhost/cgi-bin/script.sh
• script runs and only prints but no sudo cmd is executed plz help

Answer 1

These lines should be

sudo convert ~/usr/lib/cgi-bin/images/* ~/usr/lib/cgi-bin/images.pdf
sudo ocrmypdf ~/usr/lib/cgi-bin/images.pdf ~/usr/lib/cgi-bin/pdf/images_ocr.pdf

Without the ~ it's a relative path to the folder in which the script is executed.

Answer 2

If you already are in cgi-bin and won't change location :

sudo convert images/* images.pdf
sudo ocrmypdf images.pdf pdf/images_ocr.pdf

so you're not dependent on your root's folder structure and only on your project's
