📘 AIX Tip - Merging PDFs like a Pro!

Got a business request to merge multiple PDF files directly on AIX nodes.

I first tried using PyPDF2, but soon realized that Ghostscript (gs) is a hidden powerhouse for PDF manipulation - especially in UNIX environments.

Here's the magic command:

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=output.pdf abbas.pdf abdul.pdf jaga.pdf

Why Ghostscript wins:

Works without Python or extra dependencies - native binary on AIX/Linux

% Handles large & complex PDFs faster and with less memory overhead

% Supports compression, font embedding, and metadata cleanup

% Converts between multiple formats (PDF ↔ PS, EPS, TIFF, PNG, JPEG)

% Ideal for automation, scheduled jobs, and batch reports

Sometimes the old-school UNIX tools still beat the modern libraries.
