Why would the PS1 export won't carry on to a sub process?
I changed PS1 value and then exported it but when I type bash to start a second process, PS1 doesn't appear changed there. How is this possible?
I ask since this sequence did work for me:
MESSAGE="Hi"
export MESSAGE
bash
echo $MESSAGE
bash

Shell internal variables such asPS1should not be exported, as something set forbashis incompatible withzsh. In the interactive configuration, set the appropriatePS1.

it is exported, but the ~/.bashrc or /etc/profile or ~/.bash_profile overwrite it without question. Run bash --norc instead of parameterless bash.
