esc-m

esc-m

    The Emacs Lisp expression to be evaluated. This should be a valid Lisp form enclosed in double quotes or escaped appropriately for the shell to pass it to Emacs correctly.

The esc-m command is a utility, often a shell alias or function, designed to help execute Emacs Lisp expressions from the command line.
It essentially provides a convenient way to interact with a running Emacs instance by sending it commands without having to open Emacs and type them manually.
This is particularly useful for automating tasks or running snippets of code that manipulate buffers, files, or other Emacs features.
The command usually works by constructing a suitable `emacsclient` command. It then passes the Lisp expression as a string to Emacs for execution. esc-m simplifies using command-line utilities to interact with a running Emacs instance.

This command relies on a properly configured emacsclient setup and a running Emacs instance.
Proper quoting and escaping of the Lisp expression are crucial to prevent shell interpretation issues and to ensure correct execution within Emacs. The exact implementation of esc-m can vary depending on the user's shell configuration.

A typical implementation might look like this in .bashrc:
esc-m() { emacsclient -e "$1"; }.
Then, you can use it like this:
esc-m '(find-file "/path/to/file")'.

Instead of esc-m, some users may use `emacsclient -e` directly, defining more complex aliases, or using shell scripts to achieve similar functionality.

The esc-m command is not a standard Linux utility. It's a user-defined alias or function that has evolved over time. It enables Emacs users to leverage command line invocations for certain actions.
