I use apt-cache pkgname to retrieve the packages as



me@host:~$ apt-cache pkgnames | wc -l
62803


get 62803 results



but



me@host:~$ dpkg -l | wc -l
2336


What's the reasons which lead such a huge distinction. I presume that dpkg is super than apt.

          apt is for managing remote repositories, dpkg - for locally installed packages. They're related. apt is front end to dpkg. When you run apt-get install package it gets .deb file, and installs it via dpkg. So numbers differ because there's a lot of packages available, but only fraction is installed locally on your system.



          apt-cache can show both installed and non-installed packages, because it queries the apt cache - listing of what is available in remote repositories ( that cache is what you get when you do apt-get update). For instance,



          $ apt-cache policy terminator
          terminator:
          Installed: (none)
          Candidate: 1.91-1


          $ dpkg -l terminator
          dpkg-query: no packages found matching terminator
