This is a series of brief articles aimed at teaching Emacs to
computer professionals who are unfamiliar with it. I do not dwell on
the basics of the user interface, which can be learned from the
built-in tutorial. Instead, each article in this series will distill
one very specific command line (CLI) tool or technique that
Linux/UNIX users often use, and describe an equivalent function or
technique in Emacs. The tool or technique discussed will be specific
enough that the whole article can explain the concept in around 1000
words, and will provide examples, or specific actions to be
taken. The goal is to have a list of recipes that Linux users can
search and find quickly, and read through in just a few minutes, to
learn the most useful ways of using Emacs to solve day-to-day
problems.
