Bourne-again shell
Configuration 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 see the man page by typing man bash for a complete explanation of features or see the Bash Reference Manual.
To change your shell, see shell
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).
