BASHing Your Prompt
Customizing how your command line prompt looks like isn't just cool. It can also be rather useful. You can change your prompt by running the following command: PS1=" ". For example, PS1="[\t] [ \u@\h \W]\$ " will change your command line to something that resembles this: [21:52:01][user@hostname :~]$. To permanently change this, you'll have to alter this in ~/.bashrc
