Read on for a hands-on demonstration.

Leafpad dodges the scripting language hurdles with search-and-replace-all;

amenex responds with more homework:
time tr -sc 0-9\\n ' ' < CPV-ThreeNone.txt | awk '{ k = 0; for (i = 0; k < 4

complete, they are also more user-friendly

This is where I found out the "join" syntax used in my previous post:
https://www.howtoforge.com/tutorial/linux-join-command/
where it's said:
>> Now, if you want the second field of each line to be the common field for
join, you can tell this to the tool by

first file, the latter refers to the

joining field for the corresponding file.

I had been thinking of consecutive actions, whereas join does them in
parallel.
