Re: Re: Re: Persistence of a window's title?

Neal,

Thanks, thanks, thanks!

    I googled your prompt command, it is probably your system default.

My "/etc/bashrc" looks to be exactly the same one as in the book that 
you referenced.  That explains the particular content of PROMPT_COMMAND.

You wrote:

    ...it is the culprit and recommends "unset PROMPT_COMMAND" ...

I stumbled upon unsetting PROMPT_COMMAND when I looked at another system 
where the window titles persist... and I noticed that that system does 
not have PROMPT_COMMAND set.  I confirmed that unsetting that shell 
variable on my current system does the trick.

(I've referred to the manual page for "screen" many times, but somehow I 
missed the section that explains the "title-string escape-sequence" and 
the "title-escape-sequence".)

Thanks again,
