2.1.2 Startup Files

When Octave starts, it looks for commands to execute from the files in the following list. These files may contain any valid Octave commands, including function definitions.

octave-home/share/octave/site/m/startup/octaverc

where octave-home is the directory in which Octave is installed (the default is ‘No value for OCTAVEHOME’). This file is provided so that changes to the default Octave environment can be made globally for all users at your site for all versions of Octave you have installed. Care should be taken when making changes to this file since all users of Octave at your site will be affected. The default file may be overridden by the environment variable OCTAVE_SITE_INITFILE.

octave-home/share/octave/version/m/startup/octaverc

where octave-home is the directory in which Octave is installed (the default is ‘No value for OCTAVEHOME’), and version is the version number of Octave. This file is provided so that changes to the default Octave environment can be made globally for all users of a particular version of Octave. Care should be taken when making changes to this file since all users of Octave at your site will be affected. The default file may be overridden by the environment variable OCTAVE_VERSION_INITFILE.

~/.octaverc

This file is used to make personal changes to the default Octave environment.

.octaverc

This file can be used to make changes to the default Octave environment for a particular project. Octave searches for this file in the current directory after it reads ‘~/.octaverc’. Any use of the cd command in the ‘~/.octaverc’ file will affect the directory where Octave searches for ‘.octaverc’.

If you start Octave in your home directory, commands from the file ‘~/.octaverc’ will only be executed once.

A message will be displayed as each of the startup files is read if you invoke Octave with the --verbose option but without the --silent option.
