## NAME

**GRFID** – A tool to extract the (New)GRF ID from a (New)GRF

## SYNOPSIS

\[**-hvm**\]

**grfid** *file*

## DESCRIPTION

GRFID tries to find the (New)GRF identifier of that (New)GRF. Upon failure an error message is given, otherwise the NewGRF identifier is printed hexadecimally to stdout.

## OPTIONS

- **-h**

  Display the help message.

- **-m** *file*

  Display the MD5 checksum of the given NewGRF. For GRF container format 2 this checksum only contains the data section, i.e. it excludes the sprite section to make it easier to construct NewGRFs with different zoom levels.
