pdfgrep | search text in PDF files | Regex library

IEEE 754-2008:

7.5 Underflow

The underflow exception shall be signaled when a tiny non-zero result is detected. For binary formats, this shall be either:

a) after rounding — when a non-zero result computed as though the exponent range were unbounded would lie strictly between ±b^emin, or

b) before rounding — when a non-zero result computed as though both the exponent range and the precision were unbounded would lie strictly between ±b^emin.

The implementer shall choose how tininess is detected, but shall detect tininess in the same way for all operations in radix two, including conversion operations under a binary rounding attribute.

However, both C11 and C17..C2x (working draft — February 5, 2020, n2479.pdf) say nothing about tininess:

I have following lines :

I am sorting some files that I've created using pdfgrep, to list page numbers of certain PDFs that I have. it produced the following output:

pdfgrep works like grep except that it acts on pages instead of lines. How can I craft a regular expression with a newline character?

I want to look for a, followed by any number of characters except linebreaks, followed by b, but pdfgrep 'a[^\n]*b' doesn't work, whereas pdfgrep 'a.*b' returns results that span multiple lines. (I've examined the output with xxd to confirm that these newlines are indeed \x0A.)

I want to check if in my text exists different words. This words are in the complete text. But I don't find a regex for grep/pdfgrep with perl regex.

Is there a way to check the content of PDF Files and output a specified string?

With this shell script i get all files in a loop

I'm wanting to recursively search for strings in pdf files using pdftotext (not pdfgrep) using a bash function and passing my string of choice to it. The string must be able to handle special characters, as a minimum, spaces. As a bare command line, this works perfectly in a bash shell and demonstrates what I want to do.
