Description: Library that provides command line editing

Long Description: The GNU Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

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

--->  Staging readline into destroot

--->  Installing readline

- 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 readline with these commands:

%  man readline
%  apropos readline
%  which readline
%  locate readline
