 156 Package Manipulation:

 158         upgrade                 Upgrade all installed packages to latest version
 159         install <pkg>           Download and install <pkg> (and dependencies)
 160         install <file.ipk>      Install package <file.ipk>
 161         install <file.deb>      Install package <file.deb>
 162         remove <pkg>            Remove package <pkg>
 163
 164 Informational Commands:
 165         list                    List available packages and descriptions
 166         files <pkg>             List all files belonging to <pkg>
 167         search <file>           Search for a packaging providing <file>
 168         info [pkg [<field>]]    Display all/some info fields for <pkg> or all
 169         status [pkg [<field>]]  Display all/some status fields for <pkg> or all
 170         depends <pkg>           Print uninstalled package dependencies for <pkg>
 171
 172 Options:
 173         -d <dest_name>          Use <dest_name> as the the root directory for
 174         -dest <dest_name>       package installation, removal, upgrading.
 175                                 <dest_name> should be a defined dest name from the
 176                                 configuration file, (but can also be a directory
 177                                 name in a pinch).
 178         -o <offline_root>       Use <offline_root> as the root for offline installation.
 179         -offline <offline_root>
 180
 181 Force Options (use when ipkg is too smart for its own good):
 182         -force-depends          Make dependency checks warnings instead of errors
 183         -force-defaults         Use default options for questions asked by ipkg.
 184                                 (no prompts). Note that this will not prevent
 185                                 package installation scripts from prompting.
