3. Usage of Apt-get Install

   Apt-get Install <package>

   Download <package> and all dependent packages while installing or upgrading the package. If a package is set to hold (stop flag, it will be put aside (ie not be upgraded). For more hold details, see below.

5. How to use Apt-get remove

   Apt-get Remove [--purge]

   <package> Remove <package> and any other packages that rely on this package.--purge indicates that the package should be completely cleared (purged), for more information please see dpkg-p.

7. Usage of apt-get Update

   Apt-get Update

   Upgrade the package list from the Debian image, if you want to install any software on the day, run at least once a day, and you have to do it every time you modify the/etc/apt/sources.list.

9. The usage of Apt-get upgrade

   Apt-get upgrade [-u]

   Upgrade so the package that has been installed is the latest available version. No new or removed old packages will be installed. If a package changes dependency and requires a new package to be installed, it will not be upgraded, but is marked as hold. Apt-get update does not upgrade packages marked for Hold ( This is the meaning of hold. See below how to manually set the package to hold. I recommend using the '-u ' option at the same time, as you can see which packages will be upgraded.

11. The usage of Apt-get Dist-upgrade

    Apt-get Dist-upgrade [-u]

    Similar to Apt-get upgrade, except that Dist-upgrade installs and removes packages to meet dependency relationships. Therefore, it has certain danger.

13. Usage of Apt-cache Search

    Apt-cache Search <pattern>

    Search for packages and descriptions that meet <pattern>.

15. Usage of Apt-cache Show

    Apt-cache Show <package>

    Displays the full description of the <package>.

    Dselect, CONSOLE-APT, Aptitude, gnome-apt, are several graphical front ends of apt (some of which have to be installed before use). Here Dselect is undoubtedly the most powerful, and the oldest, the most difficult to steer
