I was looking at this question and I wondered if the following could be done from terminal. I did it in python, just want to see if it could be done from terminal, bash scripting or whatever.
Suppose I have a file that looks like so:
could it be sorted like so, by rows (lines)
or is it too complicated? I did it using python, I just want to know if it could be done so next time I might not use python. What I have done, is creating lists and sorting them.
