gdb: Server Prefix

 
 28.2 The Server Prefix
 ======================
 
 If you prefix a command with 'server ' then it will not affect the
 command history, nor will it affect GDB's notion of which command to
 repeat if <RET> is pressed on a line by itself.  This means that
 commands can be run behind a user's back by a front-end in a transparent
 manner.
 
    The 'server ' prefix does not affect the recording of values into the
 value history; to print a value without recording it into the value
 history, use the 'output' command instead of the 'print' command.
 
    Using this prefix also disables confirmation requests (See
 confirmation requests).
