How to search contents of multiple pdf files?

Question

How could I search the contents of PDF files in a directory/subdirectory? I am looking for some command line tools. It seems that grep can\'t search PDF files.<

Answer 1

My actual version of pdfgrep (1.3.0) allows the following:

pdfgrep -HiR 'pattern' /path

When doing pdfgrep --help:

• H: Print the file name for each match.
• i: Ignore case distinctions.
• R: Search directories recursively.

It works well on my Ubuntu.
