There are a number of prompt variables in the Korn shell: PS1 and PS2 are two of them. PS1 contains your primary prompt string and is displayed by the Korn shell when it is ready to read a command. If not specified, the default is $ for regular users, and # for superusers.
PS2 specifies the secondary prompt string and is displayed whenever the Korn shell needs more input. For example, when you press <RETURN> before a complete command has been given, or continue a command onto the next line with the \ character, the PS2 variable is displayed. If not specified, the default for PS2 is the > character.
$ print "Here is > another line" Here is another line
By default, the command prompt is set to the $
