CentOS 6.5, x86_64
I like tweaking my terminal prompt. It makes my life so much simpler to have some info easily available and especially to have alias shortcuts. I’m feeling generous this morning, so here’s my own .bashrc file for you. Tweak it to your own liking.
Profile .bashrc
I really like the look, but you may disagree. Here’s what it looks like in action:
For the uneducated, this file is located in your user’s root directory (not the server root directory). Here’s how you can be sure you’re in the right place:
1 | $ vi ~/.bashrc |
You are now editing the .bashrc file for the currently logged in user. In my case, I’m logged in as root.

I’m guessing you already know your way around bash so I won’t walk through the file step-by-step. It’s lightweight but still very useful. To list out the available aliases, simply type alias in the terminal:
1 | $ alias |
