If you want to install a software package, use the apt and dpkg commands.

Apt

The Advanced Packaging Tool is an Advanced interface of the Debian software package management system. It consists of several programs named as "APT. Apt-get, apt-cache, apt-cdrom, and apt-config are command line tools used to process software packages. They are also the backend of other user foreground programs, such as dselect and aptitude.

Apt-get update: update package list from/etc/apt/source. list

Apt-cache search-string description, such as the search-string Software Package

Apt-cache policy package-name displays the package version and priority.

Apt-cache show package-name: displays the description of the file.

Apt-cache showpkg package-name shows the dependency of the software package.

Apt-get install package-name install the package from the source and all its dependent packages

Apt-get upgrade: update the currently installed software package to the latest version.

We can see that some packages prevent updates (kept back)

Apt-get dist-upgrade

For example, apt-get upgrade will automatically resolve the conflict.

Apt-get remove package-names

Apt-get -- purge remove permanently deletes these packages and their configuration files

Apt-get -- purge remove gnome-panel nautilus +

When you delete a software package, if the package name is followed by a "+", the software package will be installed rather than deleted.

Apt-cache depends package-names: list all dependent packages of a specified package

Apt-cache rdepends package-names list all packages dependent on a given package

Apt-file upgrade: update the content list from the source

Apt-file search file-name: Find the software package containing the file

Apt-file search package-name: list the content of the package

Auto-apt

If you need to install the software package automatically, you can replace apt-file and install auto-apt.

Aptitude APT console interface, you need to install aptitude

Synaptic apt gui interface, you need to install synaptic

Apt-get clean

Delete the downloaded software package stored in the cache directory (/var/cache/apt/archives.

The/var/cache/apt/archives directory and all files under the/var/cache/apt/archives/partial directory will be deleted, except the locked files. When you install a software package again, APT will download it again.

Apt-get autoclean only deletes files that do not need to be downloaded again.

After selecting the software package in dselect, run:

Apt-get-u dselect-upgrade

Compare the situation with that of apt-get dist-upgrade.

You can see that many software packages installed in idea are the result of "recommended" or "recommended" of other software packages. Other software packages are installed or deleted by the dselect tool. It can be seen that the combination of dselect and APT will be a powerful tool.
