# Top 10 reasons why you should be using Eshell
Howard Abrams (he/him)

[[!inline pages="internal(2022/info/eshell-before)" raw="yes"]]

While Eshell is this quick and dirty way to run external commands, its
*dirtiness* plays into the Lisp’s *malleable* big ball of mud metaphor,
and I have a number of quick hacks that will make you want to play in
this puddle.

This will be a lightning talk that I will pre-record to show off some
features in eshell I found while diving into the source code &#x2026; stuff
you can’t do in another terminals. Did you know that \`$$\` is a special
variable that contains the output from the last command?

Update from Howard: I wrote an _expanded transcript_ with more code and functional links. See <http://howardism.org/Technical/Emacs/eshell-why.html>
Want _all_ the code? See my literate dotfiles for #emacs at <https://github.com/howardabrams/hamacs/blob/main/ha-eshell.org>
