grfdiff (1) Linux Manual Page

NAME

GRFDiff – A tool to create a binary GRF diff from to GRFs.

SYNOPSIS

grfdiff [-hnxyv ] [-l numbers ] [-o GRF-File ] Original-GRF-file New-GRF-file

Compare the two GRF files and produce a GRD file containing only the sprites from the second file that are different from the first file.

GRFDiff makes a .GRD file with the same basename as the new GRF file.

OPTIONS

-h

Display the help message.

-l numbers

Save the sprites with these numbers in the .GRD instead of finding the modified sprites. With this option, the first GRF file can be omitted.

Format of the numbers: <from1>[-<to1>][,<from2>[-<to2>]]… e.g. 1-5,8,20-31 (must be increasing numbers).

-n

Only show a list of modified sprites, don’t make a .GRF file.

-x

Make a self-extracting (.EXE) file instead of a .GRD.

-y

Answer ‘y’ to all questions.

-v

Display the version.

You can specify several sets of GRF files along with their –l options by separating them with a double-dash `–‘. The result will be written to a single .GRD file. Only –l is valid after the first set.
