Verify that the KornShell library is part of your operating system.

1. To verify that KornShell is part of your operating system, enter one of the following commands:

   usr/bin/ksh

   or

   /bin/ksh 

2. If these commands do not work, enter the following command to confirm that KornShell is installed:

   rpm -qa | grep ksh
   ksh-20100202-1.el5

3. If KornShell is not installed, download it and use the following command to install it:

   rpm -ivh ksh-<version>.rpm

   where <version> is the version that you downloaded.
