--sparse=WHEN
A `sparse file' contains `holes' - sequences of zero bytes that
do not occupy any physical disk blocks; the `read' system call
reads these as zeroes. This can both save considerable disk
space and increase speed, since many binary files contain
lots of consecutive zero bytes. By default, cp detects holes
in input source files via a crude heuristic and makes the
corresponding output file sparse as well.
The WHEN value can be one of the following:
auto The default behavior: the output file is sparse if the
input file is sparse.
always Always make the output file sparse. This is useful when
the input file resides on a filesystem that does not
support sparse files, but the output file is on a
filesystem that does.
never Never make the output file sparse. If you find an
application for this option, let us know.
==================
and
==================
-d Copy symbolic links as symbolic links rather than
copying the files that they point to, and preserve hard
links between source files in the copies.
==================
Is this not what you were referring to?
Also, Gregory, my Linux man page says that -S handles suffixes in the
case that the destination file already exists, and -H handles symbolic
links only. I wouldn't think GNU cp would differ as much as that from
cps in other lands.
