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).
