debuild:tldr:70859

The debuild -b command is used in Debian-based systems to compile a source package into a binary package.

Here's a breakdown of the command:

• debuild: This is the main command to build Debian packages. It is part of the devscripts package, so make sure it is installed on your system.
• -b: This option indicates that you want to build the source package into a binary package. The source package typically includes the source code and other necessary files, while the binary package contains the compiled binaries that can be installed on the system.

When you run debuild -b, the command will look for the necessary source files and build the package according to the rules specified in the package's debian directory. It will compile the source code, package the resulting binaries, and generate the .deb file(s) ready for installation.

It's important to note that using debuild -b assumes you have already set up the necessary files and configurations for building Debian packages, such as the debian/control file which describes the package and its dependencies, as well as any necessary build instructions in the debian/rules file.
