I am trying to use the gpkg -get-selections command on Ubuntu. I am kind of new to Ubuntu and really just following a tutorial on how to properly install Tomcat :)\
The tutorial is here: http://www.howtogeek.com/howto/linux/installing-tomcat-6-on-ubuntu/
The example is there, but locally I get this error:
dpkg: unknown option -g 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) [*].
Any ideas why this would be happening?
