grfdiff (1) Linux Manual Page
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-fileCompare 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.
