I am try by checking the install
To confirm the installation succeeded, use the following command.


$ dpkg -l 'openrtm*'

But I receives the message here?


dpkg -1 'openrtm*'
dpkg: unknown option -1

Type dpkg --help for help about installing and deinstalling packages ;
Use `dselect' or `aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;
Type dpkg --license for copyright license and lack of warranty (GNU GPL) .

Options marked produce a lot of output - pipe it through `less' or `more' !

Could you please tell my why it's worry?
