.Dd May 18, 2003 .Dt BSPATCH 1 .Os FreeBSD .Sh NAME .Nm bspatch .Nd apply a patch built with bsdiff(1) .Sh SYNOPSIS .Nm .Ar oldfile newfile patchfile .Op Ar old-extents new-extents .Sh DESCRIPTION .Nm generates .Ar newfile from .Ar oldfile and .Ar patchfile , where .Ar patchfile is a binary patch built by .Xr bsdiff 1 .
p When provided, .Ar old-extents and .Ar new-extents instruct .Nm to read specific chunks of data from the old file and to write to specific locations in the new file, respectively. Each is a comma-separated list of extents of the form .Ar offset : Ns Ar length , where .Ar offset is either -1 or a non-negative integer and .Ar length is a positive integer. An offset value of -1 denotes a sparse extent, namely a sequence of zeros that entails neither reading nor writing of actual file content.
p .Nm uses memory equal to the size of .Ar newfile , but can tolerate a very small working set without a dramatic loss of performance. .Sh SEE ALSO .Xr bsdiff 1 .Sh AUTHORS .An Colin Percival Aq cperciva (at] freebsd.org
