Absolute path prompt function for the current directory

Sometimes when I enter a deep directory, the command line displays longer path information. After configuring Bashrc to display only the last directory path, sometimes I really want to know the absolute path of the current directory, but I don't want to type the pwd command in the terminal. I hope there is a path prompt bar below, indicating the absolute path of the directory I am currently in.

Thanks

The issue does not mention any files, tests, or entry points. Start by locating the terminal prompt and lower path-bar implementation, then verify the absolute current-directory path while navigating into deep directories; the work is done when that path is consistently visible without typing pwd.
