GNU LilyPond program usage: 3.2 Command-line usage

## 3.2 Command-line usage

This section contains extra information about using LilyPond on the command-line. This may be desirable to pass extra options to the program. In addition, there are certain extra ‘helper’ programs (such as `midi2ly`) which are only available on the command-line.

By ‘command-line’, we mean the command line in the operating system. Windows users might be more familiar with the terms ‘DOS shell’ or ‘command shell’; MacOS X users might be more familiar with the terms ‘terminal’ or ‘console’. They should also consult Setup for MacOS X.

Describing how to use this part of an operating system is outside the scope of this manual; please consult other documentation on this topic if you are unfamiliar with the command-line.
