Description: Bash (bourne-again shell) is a UNIX command interpreter
Long Description: Bash is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh).

In addition, most sh scripts can be run by Bash without modification.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/bash
%  sudo port install bash  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching bash
--->  Verifying checksum for bash
--->  Extracting bash
--->  Configuring bash
--->  Building bash with target all

--->  Staging bash into destroot

--->  Installing bash

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using bash with these commands:

%  man bash
%  apropos bash
%  which bash
%  locate bash
