On Amazon EC2, the instance type you choose determines the amount of physical memory (RAM) that you get. Larger instance types with lots of RAM are more expensive. So if you want more RAM on a medium or small EC2 instance, you can define some storage space on your disk to act as RAM when needed. The disk area you use for this purpose is called a swap file. This article explains swap files and demonstrates how to set up a 2GB swap file using ephemeral storage on an m3.medium instance of Amazon EC2 that has only 3.75GB of RAM by default.
Most Linux systems have a default bash prompt in one color that tells you your user name, the name of the machine you’re working on, and some indication of your current working directory.

You can even change the colors either to make it look interesting, or to make certain information stand out. You might also want to customize your bash prompt if you have difficulties using the terminal because the prompt isn’t visible enough.
