Start bash process with changed prompt PS1

Question

How do I start a bash subprocess with a changed prompt. Using env does not work:

env PS1="change >" bash --login

does not work. The result should be the same as using export after the process is started:

$ export PS1="change >"
change >

~/.bashrc has to be evaluated as usual.

Answer 1

Another solution would be:

bash --rcfile <(cat ~/.bashrc; echo 'PS1="change > "')

This keeps the aliases and co by executing and "extended" version of the users startupfile.
