Slackware :: Display The Full $PROMPT_COMMAND Environment Variable In The Konsole Title Bar?

IN 3.5.10 I am able to display the full $PROMPT_COMMAND environment variable in the Konsole title bar. Kind of handy and I did not need to display that information in the $PROMPT variable.

In 4.5.5 I am having trouble figuring out how to make that work correctly. The title bar displays only the directory name rather than the full path and user name.

This is my $PROMPT_COMMAND:

history -a;echo -ne "33]0;${USER}@`uname -n`: ${PWD}07"

All I see in the title bar is:

dirname: bash

I should see:

username@hostname: full path to present working directory
