in thread Find file that contains "....." (command in Unix)

The -r option on grep is not uniformely supported. It's not in the POSIX standard. The question was about a Unix command; and GNU stands for "GNU is Not Unix". ;-)

    And if you're going to depend on non-standard grep options why not just depend on using zsh and use grep '\.\.\.\.\.' ./**/*.txt to let the shell do the find for you.

    (Aside: zsh rules.)

      Except that you run into trouble if you have to pass more files than will fit on a command line in your system.

      Makeshifts last the longest.

        No trouble at all, just a slightly different incantation.

        print -l ./**/*.txt | xargs grep '\.\.\.\.'

        (well, no trouble except that if your filenames may have spaces in them you'll need to use `-N' rather than `-l' and a GNUish xargs --null, but I digress . . .).
