Ambit uses Bash brace expansion to expand and list hostnames or commands. Ambit is first and foremost meant to be a general purpose hostlist enumerator for use by other applications or scripts. Ambit can be used to manage HostGroups from the context of a user, a system, or a network. Ambit is also able to enumerate and execute commands that contain expandable elements. Commands passed to Ambit are expanded into separate statements and executed synchronously. This means Ambit can expand and execute just about anything on the command-line and often works in situations where Bash brace expansion would probably fail.
Autojump is a tool that acts as a complement to cd: it makes navigating your filesystem a lot faster. It works by automagically maintaining a database of the directories you use the most from the command line, and allows you to jump back and forth between them, by typing just a few letters of the name of the directory you want to jump to. It works for Linux, Mac, and Cygwin under Windows.
