Ordinarily, issuing Ctrl-D at the prompt will log you out of an
interactive shell. This can be annoying if you regularly need to type
Ctrl-D in other situations, for example, when trying to disconnect from a
Telnet session. In such a situation, hitting Ctrl-D once too often will
close your shell, which can be very frustrating. This option disables the
use of Ctrl-D to exit the shell.
