There is a web site on all the prompt strings

PS1    The  value  of  this parameter is expanded (see PROMPTING
below)
       and used as the primary prompt string.   The  default  value is
       ``\s-\v\$ ''.
PS2    The  value of this parameter is expanded as with PS1 and used
as
       the secondary prompt string.  The default is ``> ''.
PS3    The value of this parameter is used as the prompt for the
select
       command (see SHELL GRAMMAR above).
PS4    The  value  of  this  parameter  is expanded as with PS1 and
the
       value is printed before each command bash displays during an
ex-
       ecution trace.  The first character of the expanded value of
PS4
       is replicated multiple times, as necessary, to indicate
multiple
       levels of indirection.  The default is ``+ ''.
