How do I change the command line default prompt λ for bash? 如何更改 bash 的命令行默认提示符 λ ？

根据 https://github.com/cmderdev/cmder#changing-cmder-default-cmdexe-prompt-config-file 页面上的说明，只有更改 CMD 环境命令提示符的方法，但没有更改 bash 环境下命令提示符的方法，我后来自己找到了是在 $CMDER_ROOT/vendor/git-for-windows/etc/profile.d/git-prompt.sh 文件中更改，但根据 https://github.com/cmderdev/cmder#upgrading 的说明，升级后我所做的修改将被删除，并且

Editing files under [cmder_root]/vendor is not recommended since you will need to re-apply these changes after any upgrade. All user customizations should go in [cmder_root]/config folder.

那么在 [cmder_root]/config 目录中修改哪个文件是可以改变 bash 的默认命令提示符的呢？或许在 [cmder_root]/config/profile.d 目录中我可以自己单独写一个 shell script 文件来更改提示符，但对我这个不熟悉 bash shell 的人来说这有些困难，所以最好有个现成的文件来修改。
另外在此问题上的一个扩展问题：如何根据启动 bash 的状态来自动设定命令提示符？如果以非管理员模式启动则显示 $ ，如果以管理员模式启动则显示 # 。

According to the instructions on the https://github.com/cmderdev/cmder#changing-cmder-default-cmdexe-prompt-config-file page, there is only a way to change the command prompt in the CMD environment, but there is no way to change the command prompt in the bash environment. I found it myself in $CMDER_ROOT/vendor/git-for-windows/etc/profile.d/git-prompt.sh, but according to https://github.com/cmderdev/cmder#upgrading, the changes I made will be deleted after the upgrade and the command prompt will be deleted. The changes I made will be deleted after the upgrade, and

Editing files under [cmder_root]/vendor is not recommended since you will need to re-apply these changes after any upgrade. All user customizations should go in [cmder_root]/config folder.

So which file in the [cmder_root]/config directory can be changed to change bash's default command prompt? I could probably write my own shell script file in the [cmder_root]/config/profile.d directory to change the prompt, but that's a bit difficult for someone unfamiliar with the bash shell, so it's better to have a ready-made file to change.
An extension to this question: how to automatically set the command prompt according to the state in which bash is started? If started in non-administrator mode it shows $, if started in administrator mode it shows #.

You can indeed write custom config *.sh scripts in $CMDER_ROOT/config/profile.d or you can edit $CMDER_ROOT/config/user_profile.sh whichever you prefer.
