\v     the version of bash (e.g., 2.00)
\V     the release of bash, version + patch level (e.g.,
       2.00.0)
\w     the current working directory, with $HOME
       abbreviated with a tilde (uses the value of the
       PROMPT_DIRTRIM variable)
\W     the basename of the current working directory, with
       $HOME abbreviated with a tilde
\!     the history number of this command
\#     the command number of this command
\$     if the effective UID is 0, a #, otherwise a $
\nnn   the character corresponding to the octal number nnn
\\     a backslash

       could be used to embed a terminal control sequence
       into the prompt
