Actually it is documented on Solaris in the man page for ls. Search for "plus sign". I can't speak for the Red Hat man pages. It indicates the presence of ACLs beyond the standard unix permission bits. > Second, when we use "cp -p" to copy any file that has the + symbol, we get: > > #cp -p filename /tmp > cp: preserving permissions for `/tmp/filename': Operation not supported I assume this is on the linux client end, since Solaris gives a more useful message: # cp -p foo /tmp cp: failed to set acl entries on /tmp/foo I suspect that your /tmp filesystem does not support ACLs, as is the case in Solaris by default, and that cp is warning that it can't do all that you asked (with -p) and preseve the ACLs of the source on the destination Boyd
