If you want to add new resource values to the resource database without overriding the current values, you must use the -merge option with the xrdb client.
For example, to add new resources that are stored in a file
called myresources, you would enter:
xrdb -merge myresources
As another example, if you wanted to configure subsequent
versions of scoterm to display scroll bars,
you could use standard input and enter:
When you are finished, press <Ctrl>d to end the standard input.
Any new resource specifications that you add during a Graphical Environment session will not affect any clients that are currently running. If you want your current clients to reflect your new resource settings, you need to restart them.
If your specifications do not seem to work, use the -query option to list the current values in the resource database. Check this list for any conflicting resource specifications.
