DPKG is Debian

DPKG is the Debian-Linux Release Technology-Debian information. The following is a detailed description. What are the essential differences between multiple Linux releases? File Systems, memory management, and process scheduling all the core features of the operating system are in the kernel package. All releases are the same. The differences are all at the application level. The main difference is the richness of the binary software package provided and the ease of installation. In this way, the unique software installation method of the Debian series of dpkg is the core of Debian, I don't know if this understanding is correct.

Linux really needs to be unified. Although the compatibility polymorphism is the source of life, the incompatibility of programs in the binary layer is indeed confusing. Even if the source code is provided, the average person will not be willing to configure, make will install the program in this way, and the compilation time of a larger program may exceed the convenience or convenience.

The Debian way

Apt-get update _ Packages file (package database) in/var/lib/apt/lists)

CD-ROM add source. list file apt-cdrom add
# Apt-get install nano-tiny-s (? Simulate)
# Apt-get install nano-tiny-d (? Download-only)
# Apt-get? Reinstall install nano
Apt-cache search mysql-server
Apt-cache show mysql-server
Apt-cache depends mysql-server

Apt-file is mainly used to determine which software package provides a file.
Apt-file search filename apt-file list packagename apt-file update

Apt-get remove vim

To completely delete these packages and their configuration files

Apt-get remove vim? Purge

How to clear software libraries downloaded to a local device

Upgrade within version. You only need one command to complete the update:

# Apt-get upgrade this command is useful when the-u option is added. This option enables APT to display the complete list of updatable software packages.
