Use absolute tool paths if not on PATH.

5. Using scripting languages (Python) for flexible needs

Python offers libraries to handle both formats and create rich reports.

• PDFs: PyPDF2 or pikepdf
• TIFFs: Pillow (PIL)

Example script:

python
Copy CodeCopied
from PyPDF2 import PdfReader from PIL import Image, ImageSequence import os, csv 
def pdf_pages(path):
    return len(PdfReader(path).pages)

def tiff_pages(path):
    with Image.open(path) as img:
        return sum(1 for _ in ImageSequence.Iterator(img))

with open(‘counts.csv’,‘w’,newline=“) as csvf:
    writer = csv.writer(csvf)
    writer.writerow([‘file’,‘pages’])
    for root,_,files in os.walk(‘docs’):
        for name in files:
            p = os.path.join(root,name)
            if p.lower().endswith(’.pdf’):
                writer.writerow([p,pdf_pages(p)])
            elif p.lower().endswith((’.tiff’,’.tif’)):
                writer.writerow([p,tiff_pages(p)])

6. Tips for reliability and performance

• Corrupted files: Tools may fail on damaged PDFs/TIFFs. Detect errors and log them separately.
• Large files: For huge PDFs, use stream-friendly libraries (pikepdf) rather than fully loading into memory. For TIFFs, iterate frames rather than converting images.
• Batch sizes: Break very large batches into chunks to avoid timeouts or memory spikes.
• Parallel processing: Use GNU parallel, xargs -P, or concurrent.futures in Python to speed up large folders.
• Preserve timestamps: When generating reports, include file modified times if auditability matters.

7. When to integrate into production workflows

• Use command-line or scripted approaches for scheduled jobs (e.g., nightly counts).
• Add logging, retries, and error alerts in automation.
• Store results in CSV or a database for quick queries and dashboards.

8. Troubleshooting common issues

• Pages reported as 0: file likely encrypted or corrupt — try opening manually.
• Different tools report different counts: ensure they’re counting the same thing (frames vs. logical pages) and test with sample files.
• Multi-page TIFFs saved as single-layer images may require re-encoding to standard multipage TIFF.

9. Recommended setup (small-to-large scale)

• Small single-user: Preview/IrfanView + manual checks.
• Medium: ImageMagick + pdfinfo scripts with periodic cron/Task Scheduler jobs.
• Large/enterprise: Python services using pikepdf and Pillow, database logging, parallel workers, and monitoring.

Conclusion

• For one-offs, use OS previews or GUI apps. For repetitive or large-scale tasks, use command-line tools or Python scripts to count pages quickly, reliably, and produce audit-ready reports.
