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 (
confirmation requests).
