Check Text (C-215188r958400_chk)
If AIX CDE (X11) is not used, this is Not Applicable.
Check the system to determine if "X11.apps.clients" is installed:
# lslpp -L X11.apps.clients
If the "X11.apps.clients" fileset is not installed, this is a finding.
Check if "xlock" command exists using the following command:
# ls /usr/bin/X11/xlock
The above command should display the following:
/usr/bin/X11/xlock
If the above command does not show that "/usr/bin/X11/xlock" exists, this is a finding.
