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/ksh93
%  sudo port install ksh93  
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 ksh93
--->  Verifying checksum for ksh93
--->  Extracting ksh93
--->  Configuring ksh93
--->  Building ksh93 with target all

--->  Staging ksh93 into destroot

--->  Installing ksh93

- 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 ksh93 with these commands:

%  man ksh93
%  apropos ksh93
%  which ksh93
%  locate ksh93
