It's a setting in the shell you use. For example, in tcsh, you
can set the `ignoreeof' shell variable to control this behaviour:
ignoreeof
If set to the empty string or `0' and the input
device is a terminal, the end-of-file command
(usually generated by the user by typing `^D' on
an empty line) causes the shell to print `Use
"exit" to leave tcsh.' instead of exiting. This
prevents the shell from accidentally being killed.
If set to a number n, the shell ignores n - 1 con-
secutive end-of-files and exits on the nth. (+) If
unset, `1' is used, i.e. the shell exits on a sin-
gle `^D'.
