quit command — LAMMPS documentation

# quit command

## Syntax

    quit status

status = numerical exit status (optional)

## Examples

    quit
    if "$n > 10000" then "quit 1"

## Description

This command causes LAMMPS to exit, after shutting down all output cleanly.

It can be used as a debug statement in an input script, to terminate the script at some intermediate point.

It can also be used as an invoked command inside the “then” or “else” portion of an if command.

The optional status argument is an integer which signals the return status to a program calling LAMMPS. A return status of 0 usually indicates success. A status != 0 is failure, where the specified value can be used to distinguish the kind of error, e.g. where in the input script the quit was invoked. If not specified, a status of 0 is returned.
