The uninstall Utility

The uninstall utility removes SIMS and other related files and packages from your system. You can specify uninstall to perform a standard or dramatic procedure.

Note - uninstall may not remove certain packages that are likely to have been installed by a separate application and may be used by that application. This is the case even if SIMS has installed that package upon setup.

The syntax for using this command is:
uninstall [-c sims] | [-d sims]
The options for this command are:
