init.m

• Mathematica initialization files contain start-up code to be evaluated whenever a Mathematica kernel or front end is launched.

• Possible locations for init.m files include the following:

• The user-specific initialization files within $UserBaseDirectory are read after the systemwide initialization files within $BaseDirectory, so any conflicting symbols will be defined as in the user-specific initialization files.

• Mathematica will also load init.m files from Autoload directories.

• To suppress the loading of kernel initialization files, use the kernel command-line option -noinit.

• To specify another file to be used for kernel initialization in addition to init.m, use the kernel command-line option -initfile file, where file is the additional initialization file.

• Template initialization files for the kernel are created automatically if they do not already exist.

• If front end options are changed while Mathematica is running, the user-specific front end initialization file will be updated automatically to reflect these changes. The systemwide front end initialization file will remain unchanged.
