The difference and connection between aptitude and Apt-get in Ubuntu (Debian)

Like Apt-get, Aptitude is the most powerful package management tool in Debian and its derivative systems. Unlike Apt-get, aptitude is better at dealing with dependency issues. For example, when aptitude deletes a package, it also deletes the packages it depends on. This way, the system will not be left with useless packets, the whole system is cleaner. The following is a summary of some of the common aptitude commands, for reference only.
Command function
Aptitude update updates the list of available packages
Aptitude Upgrade Upgrade Available packages
Aptitude Dist-upgrade Upgrade the system to a new release
Aptitude Install Pkgname installation package
Aptitude Remove Pkgname Delete Package
Aptitude Purge Pkgname Delete package and its configuration file
Aptitude search String Searching package
Aptitude show Pkgname shows the details of the package
Aptitude Clean Delete the downloaded package file
Aptitude AutoClean Delete Expired package files only

Of course, you can also use aptitude in text interface mode.

• Apt-get Better solution: Source (aptitude without this function), BUILD-DEP (low version of aptitude without BUILD-DEP function)
• Apt-get is no different from aptitude: Update, upgrade (Apt-get upgrade=aptitude Safe-upgrade, Apt-get
• Dist-upgrade=aptitude Full-upgrgade)
