Do more with less

[lalligood]

First, I'm sorry for submitting a PR (#11) without reading the README more closely. Just wanted to contribute what I hope will be some useful knowledge to the project.

IMHO, less is a largely underutilized tool that can greatly improve upon, if not replace, the functionality of several other commands--namely cat & tail--as you'll see in my PR. Also less is a tool of convenience because how many times have you opened a file with it, then exited less to open it in your editor? Yet you can jump straight into your editor from within less! Lastly, you can view multiple files with less in a manner--and keystrokes--akin to changing buffers in vim.

I added contributing guidelines to README only recently, long after you'd submitted PR..

not really sure if I want to add them, hence I left it as such.. probably should've at least commented to let you know my thoughts..

when I started this repo, I was mostly improving upon content I already put in https://github.com/learnbyexample/Linux_command_line repo.. in hindsight less doesn't belong much as cli text processing tool(as in other than viewing text) and could've been just a note in Text Editors section.. you can see that tail -f is not explained in this repo and some features of cat are given as further reading... imo, cat/tail/less serve very different purposes and are not meant as replacement for each other..

I'd suggest to open an issue in https://github.com/learnbyexample/Linux_command_line repo, discuss and then submit it as PR there...
