Varies with the vendor: Sun Solaris says
-s Uses full pathnames (as opposed to sym-
bolic links) to file rather than trying
to copy them. This means file should
not be modified or removed until it has
My trivial tests show the -r option removes the
source file when -s is ued on Solaris, so -r applies
to -s. On older systems, -s -r only removes the link.
(ie, the -r really doesn't apply at all!). Therefor,
-r -s will do fine on Solaris, but leave junk on other
Too little in the spec, too much left to the implementor.
