27.2. The Server Prefix
To issue a command to gdb without affecting certain aspects of
the state which is seen by users, prefix it with server . This
means that this command 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.
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.
