emacsclient can not do? With a running Emacs instance in which<br>
(server-start) has been called before, the following commands on a<br>
terminal with the bash shell work out of the box for me:<br>
<br>
$ emacsclient -e "(+ 1 1)"<br>
2<br>
<br>
$ printf "How many is binary? $(emacsclient -e '(+ 1 1)')\n"<br>
How many is binary? 2<br>
<br>
$ emacsclient -e 'emacs-version'<br>
"27.2"<br>
<br>
$ emacsclient -e '(with-current-buffer "*scratch*" (insert "Hello scratch buffer"))'<br>
nil<br>
=> Text was inserted into buffer *scratch*<br>
<br>
<br>
At least on this (arch) linux machine, the default server-socket-dir of<br>
"/run/user/1000/emacs" seems to be working fine.<br>
