When done, run that script with or without filenames as arguments. Save this script as a may need to edit the paths to emacs and emacsclient at the beginning of the script. ![]() For how to do this on various platforms, read on. If you tend to have a lot of windows open, and you don’t want to scan them all to verify whether one of them is Emacs or not, you might prefer to type a single command, or drag and drop onto a single icon, which is smart enough to open a file in an already running instance of Emacs, or start a new instance if Emacs isn’t running. What emacsclient does not do is start emacs if it isn’t already running. You can also run arbitrary lisp forms using the command emacsclient -eval (lisp-code-here). To start Emacs server, you add a line like this to your ~/.emacs file:įrom there, you can open a file using the command emacsclient FILE, where FILE is the path to a file. Emacs comes with Emacs server, which allows you to open a file in an already running instance of Emacs.
