### 4. Commands

This section describes how a LIGGGHTS(R)-PUBLIC input script is formatted and the input script commands used to define a LIGGGHTS(R)-PUBLIC simulation.

4.1 List of all commands

#### 4.1 List of all commands

This section lists all LIGGGHTS commands alphabetically, with a separate listing below of styles within certain commands. Note that some style options for some commands are part of packages, which means they cannot be used unless the package was included when LAMMPS was built. Not all packages are included in a default build. These dependencies are listed as Restrictions in the command's documentation.
