gdb: Prompt
22.1 Prompt
===========
GDB indicates its readiness to read a command by printing a string
called the "prompt". This string is normally '(gdb)'. You can change
the prompt string with the 'set prompt' command. For instance, when
debugging GDB with GDB, it is useful to change the prompt in one of the
GDB sessions so that you can always tell which one you are talking to.
_Note:_ 'set prompt' does not add a space for you after the prompt
you set. This allows you to set a prompt which ends in a space or a
prompt that does not.
'set prompt NEWPROMPT'
Directs GDB to use NEWPROMPT as its prompt string henceforth.
'show prompt'
Prints a line of the form: 'Gdb's prompt is: YOUR-PROMPT'
Versions of GDB that ship with Python scripting enabled have prompt
extensions. The commands for interacting with these extensions are:
'set extended-prompt PROMPT'
Set an extended prompt that allows for substitutions. 
gdb.prompt, for a list of escape sequences that can be used for
substitution. Any escape sequences specified as part of the prompt
string are replaced with the corresponding strings each time the
prompt is displayed.
For example:
set extended-prompt Current working directory: \w (gdb)
Note that when an extended-prompt is set, it takes control of the
PROMPT_HOOK hook. prompt_hook, for further information.
'show extended-prompt'
Prints the extended prompt. Any escape sequences specified as part
of the prompt string with 'set extended-prompt', are replaced with
the corresponding strings each time the prompt is displayed.
