PROMPT_COMMAND+=$'\n''my new stuff'
Or, test whether PROMPT_COMMAND is currently empty, and only
append the newline (or semicolon) if it's
Hi,
I'd like to second this feature request.
As Daniel mentioned, the biggest problem with the current single
variable approach that it's hardly usable due to lack of coordination
between distributions as well as apps that wish to modify
PROMPT_COMMAND. Let's look at it at more details.
There is
Sure, but you have a coordination problem. Everyone is going to use a
different array name, and since scripts have no way of knowing in advance
to what array they need to add their function, we end up the same spot.
Putting the array in the core would solve the coordination problem.

easier to manipulate the list of commands programmatically) but then
you can't
