Hi Kelvin,

Bash automatically expands "\$" in PS{1,2} to "#" for user ID 0 and "$" 
for any other user ID.

PS2 is used when additional input is needed from the user, such as in the 
following example:

  syncman@viper ~$ echo PS2=\'$PS2\'
  PS2='> '
  syncman@viper ~$ for x in hello world
  > do echo $x
  > done
  hello
  world
  syncman@viper ~$ 

See the PROMPTING section in the bash(1) manual page for more information.

        - Syncman.
