The dpkg-deb command is a package management tool for Debian Linux. It is used to create, extract, and manipulate Debian packages in the .deb format. This command is used to install and manage packages on Debian-based systems.
Overview
The dpkg-deb command is used to create, extract, and manipulate Debian packages. The command can be used to create a new package, extract files from an existing package, and perform various other operations on a package.
Creating a New Package
To create a new package using dpkg-deb, you will need to have the files you want to package in a directory. Once you have the files ready, you can use the following command to create a package:
dpkg-deb --build <directory> <output.deb>
In the above command, <directory> is the directory containing the files you want to package, and <output.deb> is the name of the package you want to create.
Extracting Files from a Package
To extract files from an existing package, you can use the following command:
dpkg-deb --extract <package.deb> <directory>
In the above command, <package.deb> is the name of the package you want to extract files from, and <directory> is the directory where you want to extract the files.
Other Operations
dpkg-deb can also perform other operations on a package, such as:
--info <package.deb>: Display information about a package.--contents <package.deb>: Display the contents of a package.--fsys-tarfile <package.deb>: Create a tar file of the package’s file system tree.
