A.7.5 Termination

Exit[ ] or Quit[ ]	terminate Mathematica
$Epilog	symbol to evaluate before Mathematica exits
$IgnoreEOF	whether to exit an interactive Mathematica session when an end-of-file character is received
end.m	file to read when Mathematica terminates

There are several ways to end a Mathematica session. If you are using Mathematica interactively, typing Exit[ ] or Quit[ ] on an input line will always terminate Mathematica.

If you are taking input for Mathematica from a file, Mathematica will exit when it reaches the end of the file. If you are using Mathematica interactively, it will still exit if it receives an end-of-file character (typically d). You can stop Mathematica from doing this by setting $IgnoreEOF=True.
