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

Then difference images is generated in the sub-sub-folder RegTestDiffImages based on the images in sub-sub-folder RegTestBaseImages. 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.
