.deb ??

Using Ubuntu Linux, I came across .deb files quite often.

Basics

.deb is Debian package.

dpkg -i [package_name.deb] installs the application.

Structure

• Magic + Package Section : format version number.
• Control Sectionn .tar.gz : Package meta-info (e.g. dependencies…)
• Data Section .tar.gz : Actual installable files.

There was a dependency problem of installing .deb file, hence apt is developed!

apt package manager uses dpkg to install Debain packages.
