hah, managed to get rdiff working.. djeezes, it's a two pass technique, why don't they explain it in man page? rdiff signature ORI.file S.sig rdiff delta S.sig MODI.file D.rdiff or in one go: rdiff signature ORI.file | rdiff delta -- - MODI.file D.rdiff with ORI.file your original file MODI.file your modified file and D.rdiff as your diff file to patch: rdiff patch ORI.file D.rdiff it seems a bit more cumbersome than simply to do: diff ORI.file MODI.file > D.diff On Mon, 17 Aug 2009, Kenny Billiau wrote:
Hi,
anyone any idea how to diff two 13GB files without running out of memory? Apparently gnu diff loads both files into memory and compares :/
I've tried out rdiff from non-gnu, but I don't seem to be able to get it working :/
Any suggestions are welcome.
Kenny.
