A shell script that runs OCRmyPDF with options suitable for document archival in PDFs while supporting text search and file optimization. Meant to be used in any platform that supports Homebrew, but can be adapted to any other Linux/Unix platform so long as the OCRmyPDF and tesseract dependencies are installed.
#!/bin/bash
# This script performs OCR on a PDF file using OCRmyPDF,
# optimizes images and document layout.
#
# Uses OCRmyPDF - https://github.com/ocrmypdf/OCRmyPDF

# Dependencies:
# - `brew install tesseract-lang`` # Option 2: for all
# language packs (to support spanish and others)

.SYNOPSIS
Checks if a specified port on a given hostname is open or closed, with a simplified output.
.DESCRIPTION
This script uses the Test-NetConnection cmdlet to attempt a TCP connection to a specified hostname and port.
It then checks the result of this attempt to determine if the port is open (indicating the host is listening on that port)
or if the port is closed/not reachable. The result is printed to the console with a color-coded message.
