top (the UNIX process inspector) cheat sheet

This is a list of the most helpful keyboard commands I use within top.

The basics

h shows help on interactive commands. Also see the top manual page

q to quit the program.

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

XCode is installed (via the App Store)
XCode command line tools are installed (xcode-select --install will prompt up a dialog)
Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Intro

TCL-Expect scripts are an amazingly easy way to script out laborious tasks in the shell when you need to be interactive with the console. Think of them as a "macro" or way to programmaticly step through a process you would run by hand. They are similar to shell scripts but utilize the .tcl extension and a different #! call.

Setup Your Script

The first step, similar to writing a bash script, is to tell the script what it's executing under. For expect we use the following:

#!/usr/bin/expect
