MathKernel


starts the Mathematica kernel in Windows and Mac OS X.
MORE INFORMATION
  • runs the standalone Mathematica kernel. To access the full Mathematica system including the notebook interface, use Mathematica.
  • A standalone kernel session normally reads input from (typically a keyboard), evaluates the expression, and prints the results to (typically a display device). Input and output can be redirected using Mathematica commands or standard shell mechanisms.
  • The following command-line options can be given:
-mathlinkcommunicate only via MathLink
-initfile "file"execute the commands in the initialization file during startup
-lmverboseprint information on interactions with MathLM
-noinitdo not read any initialization files
-password "pw"use the password
-pwfile "file"read passwords from
-run cmdrun on startup
-nopromptdo not print banner or In/Out prompts (useful for batch input)
-script "file"execute the commands from the in a script mode
  • If the -script command-line option is given, the kernel evaluates commands from the in a batch, or script, mode and then terminates.
  • In a script mode the kernel prints no banner and no In or Out labels, and generates all output in InputForm, with the PageWidth option effectively set to Infinity.
  • In a script mode the standard input and output are not redirected, so that the input and output can be used in a pipe with other processes.
  • In a script mode the kernel ignores the first line of the file if it starts with the characters "#!".
  • The following command-line option can be used in Windows:
-threadpriority=nset the relative priority of the kernel process
  • The argument to -threadpriority option can be one of -2, -1, 0, 1, or 2, with the default being 0. Positive numbers indicate that the kernel should run at a higher priority than normal, while negative numbers indicate a lower-than-normal priority.
  • If no command-line options are given, the kernel will read the value of the environment variable and will use that value as though it had been entered on the command line.
  • Unless the Mathematica variable $IgnoreEOF is set to True, the kernel will exit when it receives an end-of-file character sequence. The kernel will always exit when given the command Quit.
