 PJB> emacs is an interactive program.  It expects its stdin and stdout
 PJB> to be hooked to the terminal, where it can display a character
 PJB> matrix, and from which it can read user input.

[...]

 PJB> To open several files in emacs, you could either use emacsclient,
 PJB> or an emacs lisp script.

 PJB> Launch emacs in a separate terminal: xterm -e emacs -nw &

 PJB> In emacs, start the server: M-x server-start RET

 PJB> In a shell, you can then type: find -name '*.txt' | xargs
 PJB> emacsclient -n

        Note that a separate terminal is not necessary, as one can call
        Shell commands from Emacs, like:

$ emacs -nw 
...
M-x server-start RET
...
M-! find -name '*.txt' | xargs emacsclient -n & RET

        But one has to use an “asynchronous” (i. e., “background”)
        command, as indicated by an ampersand after the command line.

 PJB> Simplier would be to just open the file in emacs:

 PJB> Launch emacs: emacs -nw Then type: C-x C-f *.txt RET

        Though that will not recurse into the directories, as the plain
        find will.
