I tried the GNU ed
I tried the GNU ed text editor for the first time. I first heard about it from Brain W. Kernighan in a YouTube video, which made me decide to try it.
Gnu ed is an line-oriented text editor. It is used to create, display, modify and other wise manipulate text files, both interactively and via shell scripts. Ed is the 'standard' text editor in the sense that it is the original editor for Unix, and thus widely available.
