.SH "NAME"
nfs-cp \- Utility to copy files to/from and NFS server

.SH "DESCRIPTION"
.PP
nfs\-cp is a utility to copy files to/from and NFS server\&.
.PP
When the source is read over NFSv4\&.2, nfs\-cp copies sparse files sparsely\&. It asks the server where the data is, using the SEEK operation, and copies only those regions, so the holes are neither read from the source nor written to the destination\&. The destination is given the full size of the source up front and the skipped regions are left as holes in it; where the destination is also NFSv4\&.2 they are deallocated explicitly with DEALLOCATE\&.
.PP
This needs the source to be NFSv4\&.2, for example nfs://server/path/file?version=4\&.2\&. Any other source is copied in full, hole or no hole, as the holes cannot be located\&.

Examples:
.sp
.if n \{\
.RS 4
.\}
.nf
$ nfs\-cp foo\&.c nfs://127\&.0\&.0\&.1/data/tmp/foo\&.c

$ nfs\-cp nfs://127\&.0\&.0\&.1/data/tmp/foo\&.c bob\&.c

$ nfs\-cp nfs://127\&.0\&.0\&.1/data/tmp/foo\&.c nfs://127\&.0\&.0\&.1/data/tmp/copy\-of\-foo\&.c
