[[Category:.bashrc]]

== My .bash_profile ==
This is my primary file. It uses some host detection to figure out what files it should load for the colors of the prompt and then sets up most of my environment variables. It's starting to show it's age from when I switched to bash back in 1997. Ooohhh, compiler optimizations for 32 bit sparc platforms! There are some nifty features in this that others may like. First, it's got a wicked cool prompt, well, I thought so back in 1998 when I made it. Second, I can modify and add directories to the permanent path from the command line by using the addpath command.
