# freedoom1(6)

Automatically launch Freedoom with an engine

## NAME

freedoom1 - Automatically launch Freedoom with an engine

## SYNOPSIS

**freedoom1** \[*-p* *DOOMPORT*\|*--*\] \[*ARGS*\]

## DESCRIPTION

Freedoom is a project to create a complete free-content game based on the *Doom* engine (often called “source ports” or simply “ports”), which itself is free software.  In addition, it maintains compatibility with *Doom* itself and is capable of playing the wide variety of modifications (“mods”) that have been released by an active community since 1993.

This command is a simple shell script to assist in running Freedoom, which is not a game engine itself nor part of any engine project, but playing Freedoom should remain simple.  The script tries to automatically select an engine based on a hard-coded list, but three overrides are available, in order of precedence: command-line argument, environment variable, and a $HOME/.doomport symbolic link. Passing *-p DOOMPORT* runs Freedoom using the *DOOMPORT* specified. Setting the *DOOMPORT* environment variable is similar, running the engine specified in the variable.  An additional permanent setting is via the $HOME/.doomport symbolic link, which may point to an executable to run.

Additional arguments passed to the program, or after specifying *--* as the first option, will be passed to the engine being called.  This can allow you to use options such as *-file* to load mods or anything else available with the engine of choice.
