The main and friendlier frontend to dpkg is aptitude. DPKG itself is completely controlled by command-line parameters, which contain only an action and zero or more options. Action arguments tell dpkg what to do, options control how actions behave in some way.
'dpkg' is mainly used to install the 'deb' software package that has been downloaded locally, or to manage the installed software.
aptAnd 'apt-get' is a tool similar to Red Hat yum, which can resolve debpackage dependencies by itself. Download and install software directly from a remote software repository. The apt command can refer to the Linux apt command
