parse

#!/bin/bash
#
# Unified PDF parser - runs 8 different PDF parsing libraries
#
# Usage:
#   ./parse <pdf_file>
#
# Output (8 files):
#   Python:
#     <filename>.pdfminer.txt   - pdfminer.six
#     <filename>.pymupdf.txt    - PyMuPDF
#     <filename>.pdfplumber.txt - pdfplumber
#   JavaScript:
#     <filename>.pdfparse.txt   - pdf-parse
#     <filename>.pdfjs.txt      - pdfjs-dist
#     <filename>.pdf2json.txt   - pdf2json
#   Go:
#     <filename>.ledongthuc.txt - ledongthuc/pdf
#   CLI:
#     <filename>.pdftotext.txt  - poppler (very common in enterprise ATS)
#
# Note: Desktop folder (~/Desktop) is the default location for input/output
