# 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

```bash
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`).
