The nice thing about emacs is the customization. Unix utilities like ls, grep,… are opaque blob with switches. With Emacs, you have direct access to the functions and variables. Instead of praying for a switch or a configuration option, you just write or alter the code and integrate them together. And while you have libraries and code access, elips is easier than the unix way (writing c/go/rust/… programs or bash/perl/awk/python/… scripts). Except for few cases.
