I get around that by a pretty idiosyncratic trick, that many people would
find intolerable. I have
PROMPT_COMMAND='[ $? -eq 0 ] || play
/usr/local/lib/sounds/swish.au;youHaveMail;directory'
Where youHaveMail produces a voice sound when I have mail and it has been a
while
since that sound was last enunciated, and where directory sets the bash prompt
as a function of the host and the current directory.
Confession: I have never fixed this problem:
false|true
Then true is run and the command does not return an error value.
