    Grep may sort of also work with pdf files. You might want to also use the strings command to get "clean" srings. Note: *some* pdf files are just images (no actual text). These would be PDFs created by scanning a document (not
    using OCR). Also, many typesetting programs (TeX/LaTex, word-processos, etc), might do some typesetting "magic" (eg ligitures, etc.) that might make things hard for grep.

    xpdf includes a text search button as part of its UI.

    "ligatures"

    Text in PDFs is sometimes compressed. So one can either use
    programs like "Agent Ransack" to search for text in PDFs or
    tools like "pdftotext" to first create a text file for every
    PDF file and then grep those text files.

    PS: "Agent Ransack" is Windows software. "pdftotext" is also
    available for Linux. Converting all PDFs to text files needs
    to be done only once, and then search operations on those
    text files are faster than scanning the PDF files for text
    on every search!

    You can use pdfgrep (https://pdfgrep.org/) for that. It is
    available as a package in Fedora and Debian as well.

    I installed pdfgrep in my Kubuntu system, but it is
    not happy. Although the man file is there, even help
    doesn't work:

    I just installed pdfgrep_2.1.2-1build1_amd64.deb in my Mint 20.1 and it
    seems to work OK. What version is the Kubuntu one?
