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

There is an open source common resource grep tool crgrep which searches within PDF files but also other resources like content nested in archives, database tables, image meta-data, POM file dependencies and web resources - and combinations of these including recursive search.

The full description under the Files tab pretty much covers what the tool supports.

I developed crgrep as an opensource tool.
