Bourne-again shell
Confiruation Files
Bash has two main configuration files, ~/.bash_profile and ~/.bashrc in addition to the ones provided by the operating system. Please note that they are used differently depending on if you have started a login shell or a interactive shell.
Login shells (ssh, console) use ~/.bash_profile
Interactive shells (additional terminals in X) use ~/.bashrc
Please the MAN page by typing man bash for a complete explanation of features.
Paths
You can see your current paths (colon separated list) by the typing the following in your terminal.
echo $PATH
You can add additional paths by using the following command
export PATH=${PATH}:/the/new/path
By moving around the ${PATH} you can control the order that programs are found in your path (the path is looked up left to right).
