emacsclient: Specify an alternative editor in case no Emacs server is running.
$ emacsclient --alternate-editor ${editor} ${filename}
try on your machine
This command launches the emacsclient executable, which is a program that allows you to interact with the Emacs editor from the command line.
Here's a breakdown of the command:
emacsclient: This is the actual command to launchemacsclient.--alternate-editor ${editor}: This option specifies an alternate editor to use if Emacs is not currently running.${editor}is a placeholder that should be replaced with the name or path of the alternate editor. If Emacs is running, the file you specify will be opened in Emacs instead.${filename}: This is the name or path of the file you want to open or edit.
In summary, this command is used to open or edit a file using Emacs by first trying to connect to a running instance of Emacs (emacsclient), and if that fails, falling back to an alternate editor (${editor}).
