Which command is used to build the necessary files for an application?

The command used to build the necessary files for an application is "make." This command is part of the build process in many programming environments, especially when working with C, C++, and other compiled languages. The "make" utility automates the process of building executable programs and libraries from source code by reading a file called a Makefile. This file contains rules and dependencies required to compile and link the various parts of the application correctly.

When running the "make" command, it determines what needs to be rebuilt based on the timestamps of the source files and any existing compiled files (object files). If a source file has changed since the last build, make will recompile it and any other files that depend on it, ensuring that the final application is always up-to-date. This makes "make" an essential tool for software development in a Linux environment, facilitating efficient builds and simplifying the development workflow.
