How to run DOS programs on Linux

Operating systems are designed to run programs specifically compiled for them, as a program may rely on specific libraries or function calls. To run DOS programs on Linux, you can use virtualization or emulation methods.

DOSBox is a popular emulation program that allows you to run DOS programs on Linux systems. It is widely available in most Linux distributions and can be installed via the distribution's default package manager in the terminal.
