- 0. get you a shell
- ==================
-
- You don't have to have a shell at hand to get something out of this book.
- Still, as with most practical subjects, you'll learn more if you try things out
- as you go. You shouldn't feel guilty about skipping this section. It will
- always be here later if you need it.
-
- Not so long ago, it was common for schools and ISPs to hand out shell accounts
- on big shared systems. People learned the command line as a side effect of
- reading e-mail.
-
- That doesn't happen as often now, but in the meanwhile computers have become
- relatively cheap and free software is abundant. If you're reading this on the
- web, you can probably get access to a shell. Some options follow.
-
- ask for an account on squiggle.city
- -----------------------------------
-
- [squiggle.city][squiggle] is a server I'm running explicitly for teaching
- purposes, modeled on [tilde.club][tildeclub].
-
- You can get ahold of me by mailing bbearnes at Google's giant e-mail service,
- or on twitter [as @brennen][atbrennen]. Just let me know you'd like an account
- and I'll walk you through the basics.

-
- use a raspberry pi or beaglebone
- --------------------------------
-
- Do you have a single-board computer laying around? Perfect. If you already
- run the standard Raspbian, Debian on a BeagleBone, or a similar-enough Linux,
- you don't need much else. I wrote most of this text on a Raspberry Pi, and the
- example commands should all work there.
-
- use a virtual machine
- ---------------------
-
- _To come: Instructions for running Linux in a virtual machine on your own
- computer or using a cloud provider like Linode, DigitalOcean, or Amazon._
