Command line parameters are prefixed using a double dash. This convention is used on all platforms to make it possible to reuse scripts across different platforms.

See GNU Standards for Command Line Interfaces.

Examples on how command line options are used are given in Batch Commands

--size <width> <height> Set size of the main application window.

--replaceSourceCases [<caseGroupId>] <gridListFile> Replace source cases in <caseGroupId> or first grid case group with the grid files listed in the <gridListFile> file. Repeat parameter for multiple replace operations.

--commandFile <commandFile> Execute a command file. See command file documentation.
--commandFileProject <filename> Project to use if performing case looping for command file. Used in conjunction with commandFileReplaceCases.
--commandFileReplaceCases [<caseId>] <caseListFile> Supply list of cases to replace in project, performing command file for each case. Project to replace cases in must be set with commandFileProject. If caseId is not supplied, first case is replaced. When supplying caseId, multiple cases may be replaced at once, by supplying several caseIds and a file containing a list of grid-files to replace with for each caseId.
--help, --? Displays help text and version info
--regressiontest <folder> Run a regression test on all sub-folders starting with TestCase* of the given folder. files in the sub-folders will be opened and snapshots of all the views is written to the sub-sub-folder RegTestGeneratedImages.

The results are presented in ResInsightRegressionTestReport.html that is written in the given folder.
--updateregressiontestbase <folder> For all sub-folders starting with TestCase*, copy the images in the sub-sub-folder RegTestGeneratedImages to the sub-sub-folder RegTestBaseImages after deleting RegTestBaseImages completely.
--unittest Execute integration tests
