Overview This tutorial is written from the spective of processing lots of text data in a very quick fashion some ways that you could use this tool would be to parse log files or command output. I have used AWK to quicly parse and summarize logs that contain very small numbers of records to thousands of records. The great thing about awk is that it is included out of the box in most Unix based operating systems such as Linux, GNU, and Mac OSX.
What are VirtialBox and Vagrant and what can they do for me? VirtualBox You can use VirtualBox to run an entire sandboxed operating system within your own computer.
Vagrant You can use Vagrant to manage a development environment. Through the command line, you can download, install, configure, and run any available OS, do your work inside of it, shut it down, rebuild it on the fly, and more.
The Dynamic Duo Through the use of VirtualBox and Vagrant, you can simulate the production environment of your production server.
