pdfgrep

Search text in PDF files. More information: https://pdfgrep.org.

• Find lines that match pattern in a PDF:
  pdfgrep {{pattern}} {{file.pdf}}
• Include file name and page number for each matched line:
  pdfgrep --with-filename --page-number {{pattern}} {{file.pdf}}
• Do a case-insensitive search for lines that begin with "foo" and return the first 3 matches:
  pdfgrep --max-count {{3}} --ignore-case {{'^foo'}} {{file.pdf}}
• Find pattern in files with a .pdf extension in the current directory recursively:
  pdfgrep --recursive {{pattern}}
• Find pattern on files that match a specific glob in the current directory recursively:
  pdfgrep --recursive --include {{'*book.pdf'}} {{pattern}}
