show - show package details
update - update list of available packages
install - install packages
remove - remove packages
upgrade - upgrade the system by installing/upgrading packages

2、apt-get
# apt-get --help
apt-get is a simple command line interface for downloading and installing packages.
The most frequently used commands are update and install.
update - Retrieve new lists of packages
upgrade - Perform an upgrade
install - Install new packages (pkg is libc6 not libc6.deb)
remove - Remove packages
autoremove - Remove automatically all unused packages
purge - Remove packages and config files
source - Download source archives
build-dep - Configure build-dependencies for source packages
dist-upgrade - Distribution upgrade, see apt-get(8)
dselect-upgrade - Follow dselect selections
clean - Erase downloaded archive files
autoclean - Erase old downloaded archive files
check - Verify that there are no broken dependencies
changelog - Download and display the changelog for the given package
download - Download the binary package into the current directory
-d Download only - do NOT install or unpack archives
-s No-act. Perform ordering simulation
-y Assume Yes to all queries and do not prompt
-f Attempt to correct a system with broken dependencies in place
3、apt-cache
# apt-cache --help
apt-cache is a low-level tool used to query information from APT's binary cache files
search - Search the package list for a regex pattern
show - Show a readable record for the package
# apt-cache search docker
karbon - vector graphics application for the Calligra Suite
docker - System tray for KDE3/GNOME2 docklet applications
kdocker - lets you dock any application into the system tray
python-docker - Python wrapper to access docker.io's control socket
python3-docker - Python 3 wrapper to access docker.io's control socket
ruby-docker-api - Ruby gem to interact with docker.io remote API
docker-ce - Docker: the open-source application container engine
vim-syntax-docker - Docker container engine - Vim highlighting syntax files
4、apt-file
# apt-file --help
update Fetch Contents files from apt-sources.
search|find <pattern> Search files in packages
list|show <pattern> List files in packages
purge Remove cache files
--ignore-case -i Ignore case distinctions
--package-only -l Only display packages name
--sources-list -s <file> sources.list location
查找命令或文件来自哪个package（包括已安装的和未安装的），dpkg -S 只会搜索已安装的package。
这里跟yum provides相比体验还是差了不少，这里匹配正则pattern，会列出所有包含关键字的文件，列出众多文件之后还需要过滤，而yum provides会直接列出包含文件的package。
# aptitude install apt-file 安装apt-file，默认没有安装
# apt-file update 更新索引
# apt-file find docker | grep docker$
ansible: /usr/share/ansible/cloud/docker
docker: /usr/bin/wmdocker
docker: /usr/share/menu/docker

5、aptitude
# aptitude --help
install - Install/upgrade packages.
remove - Remove packages.
purge - Remove packages and their configuration files.
forbid-version - Forbid aptitude from upgrading to a specific package version.

Description: Docker: the open-source application container engine
Docker is an open source project to build, ship and run any application as a lightweight container
Docker containers are both hardware-agnostic and platform-agnostic. This means they can run anywhere, from your laptop to the largest EC2 compute instance and everything in
between - and they don't require you to use a particular language, framework or packaging system. That makes them great building blocks for deploying and scaling web apps,
databases, and backend services without depending on a particular stack or provider.
