Options Comments
--admindir Define the administration directory, where the database of the installed packages resides.
--build [Only with --install] Using this command along the --install command is the same as doing --build-and-install.
--debug Define a set of flags of things to print out for debug purposes.
--dry-run Run all validations then exit.
--force-all Ignore all problems that can be bypassed.
--force-architecture Ignore architecture mismatch errors.
--force-breaks Allow the installation of packages that break others.
--force-configure-any Automatically configure packages that were only unpackaged earlier.
--force-conflicts Accept packages even if they are in conflict with others.
--force-depends Accept installing packages with missing dependencies.
--force-depends-version Accept installing packages with dependencies having incompatible versions.
--force-downgrade Allow a package to be dowgraded.
--force-hold Force an upgrade to occur even if one of the explicit packages is currently on hold.
--force-overwrite Allow a package to overwrite another's file(s).
--force-overwrite-dir Allow the system to overwrite directories with files and vice versa.
--instdir Define the installation directory, where the data files are installed on the target.
--interactive Allow wpkg to interactively request a username and password when necessary to access a remote drive.
--no-act Run all validations then exit.
--no-force-all Prevent any --force-... command line option from being used.
--no-force-architecture Prevent package with an incompatible architectures from being installed.
--no-force-breaks Prevent the installation of package if marked as breaking each others.
--no-force-configure-any Do no automatically configure packaages. If a dependency is an unpacked package, then the verification fails.
--no-force-conflicts Prevent incompatible packages from being installed along each others.
--no-force-depends Prevent packages with missing dependencies from being installed.
--no-force-depends-version Prevent installing packages if dependency versions are not compatible.
--no-force-downgrade Prevent a package from being downgraded (a smaller version cannot be installed.)
--no-force-hold Prevent upgrading a package if it is currently on hold.
--no-force-overwrite Forbid any package from overwriting any file while being installed.
--no-force-overwrite-dir Prevent the overwrite feature on directory.
--quiet Request for minimal output. For the --verify function this is the default behavior.
--recursive Recursively scan the --repository directories or remove all dependencies automatically.
--refuse-all Prevent all problems from ever being bypassed.
--refuse-architecture Prevent package with an incompatible architecture from being installed.
--refuse-breaks Prevent the installation of package if marked as breaking each others.
--refuse-configure-any Do no automatically configure packaages. If a dependency is an unpacked package, then the verification fails.
--refuse-conflicts Prevent incompatible packages from being installed along each others.
--refuse-depends Prevent packages with missing dependencies from being installed.
--refuse-depends-version Prevent installing packages if dependency versions are not compatible.
--refuse-downgrade Prevent a package from being downgraded (a smaller version cannot be installed.)
--refuse-hold Prevent an upgrade of a package that is on hold.
--refuse-overwrite Forbid any package from overwriting any file while being installed.
--refuse-overwrite-dir Prevent the overwrite feature on directory.
--repository List of directories used as repositories for package dependencies.
--root Define the installation root path.
--simulate Run all validations then exit.
--skip-same-version Do not reinstall a package if that same version is already installed.
--tracking-journal Specify the filename for the tracking journal that can be used to rollback changes made by installation commands.
--verify-fields Ensure fields validity before processing.
--verbose Display log information of level INFO.

 

The --check-install command is used to verify that a set of packages can indeed be installed on a target machine. All the validation run before the installation process begins are run by the --check-install command. This includes all the validations necessary to ensure a valid directed acyclic graph once the installation is complete (that all dependencies were satisfied.)

Note that this process is different from the --dry-run used with the --install command, because a dry run checks for write permissions on the target whereas the --check-install command does not.
