Problem
I love Linux 'less' (perhaps even more than nano...). I almost always run 'less' with the -S flag (which does not wrap text passed the screen width).
This guide shows how you can set default options (per user) for 'less'.
Solution
You'll need to first create an .lesskey file in your user folder. Note, if you use sudo less, you'll need to create a .lesskey file in /root.
In your user folder, do
nano .lesskey
and add the following text:
#env LESS = -S
add any options you would like (in the above example I've just added the '-S' option).
You'll now need to run the code below to activate the default options.
lesskey
