How To Install ed on CentOS 8

ed is The GNU line editor

Introduction

In this tutorial we learn how to install ed on CentOS 8.

What is `ed`

Ed is a line-oriented text editor, used to create, display, and modify text files (both interactively and via shell scripts). For most purposes, ed has been replaced in normal usage by full-screen editors (emacs and vi, for example). Ed was the original UNIX editor, and may be used by some programs. In general, however, you probably don’t need to install it and you probably won’t use it.

We can use yum or dnf to install ed on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install ed.
