-i|--in – reads package name from input XML file.
You can generate the XML file by using the -o parameter with the getPackages command.
-ps|--packageNames – specifies one or more package names to be removed. Each package name is followed by a colon and the package version number. Use a comma to separate the information for multiple packages, with no white space; for example:
-p myPkg:2.0
Note: If you omit -ps, removePackages prompts interactively for package names to be removed.
-sl|--silent – disables all user interactive
questions; this option is generally used with batch files.
