Today, I came across Advanced Bash-Scripting Guide, which I found to be extremely useful. (For those who love techy bash/ssh stuff, it makes for good bedtime reading.) From it, I created my .bash_profile file.
For those who don't know anything about SSH, when you log into Hostgator SSH, you get something like this:
Very DOS-ish. Old School. But fast nonetheless.
If you change directories into public_html or whatever, then you get something like this:
Really!? Did it work? What happened? As I always say, "No news is good news." However, the .bash_profile that I used to create my .bash_profile is expansive and contains a lot of nifty helps, explanations, and functions. Take a look at it and try it out!
I broke it up into various copy-paste sections. See below for the full file.

| # PERSONAL $HOME/.bashrc FILE for bash-3.0 (or later) | |

| # This file is normally read by interactive shells only. | |
| #+ Here is the place to define your aliases, functions and | |
| #+ other interactive features like your prompt. | |
| # | |
| # The majority of the code here assumes you are on a GNU | |
| #+ system (most likely a Linux box) and is often based on code | |
| #+ found on Usenet or Internet. | |
| # | |
| # See for instance: | |
| # http://tldp.org/LDP/abs/html/index.html | |

| # | |
| # The choice of colors was done for a shell with a dark background | |
| #+ (white on black), and this is usually also suited for pure text-mode | |
| #+ consoles (no X server available). If you use a white background, | |
| #+ you'll have to do some other choices for readability. | |
| # | |
| # This bashrc file is a bit overcrowded. | |
| # Remember, it is just just an example. | |
| # Tailor it to your needs. | |

| #+ Here is the place to define your aliases, functions and | |
| #+ other interactive features like your prompt. | |

| #+ system (most likely a Linux box) and is often based on code | |
| #+ found on Usenet or Internet. | |

| # See for instance: | |

| #+ (white on black), and this is usually also suited for pure text-mode | |
| #+ consoles (no X server available). If you use a white background, | |
| #+ you'll have to do some other choices for readability. | |
