Extract PDF Pages

Extract a page range from a PDF file into a new PDF using pdftk.

Usage

When invoked, ask the user for (if not already provided):

1. Source PDF — absolute path to the input PDF file
2. Page range — start and end pages (e.g., 200-204)
3. Output filename — name for the new PDF (defaults to current working directory)

Command

pdftk "<source_pdf>" cat <start>-<end> output "<output_path>"

Rules

• Always use absolute paths for both source and output files.
• If the user provides only a filename (no directory), place the output in the current working directory.
• If the output file already exists, warn the user before overwriting.
• Support multiple extractions in a single invocation (run them in parallel).
• After extraction, confirm with file size: ls -lh "<output_path>"
• Requires pdftk to be installed (apt install pdftk).
