"Stay on same filesystem" is for the case in which you have another partition mounted somewhere in the tree below the current working directory. It means that you want to omit everything in that second file system. If you haven’t any such complication you don’t need to specify -x. For instance, I have separate partitions for /usr/portage and /usr/portage/packages. If I wanted to cp everything in portage but not in packages I’d specify -x. > I use this seeing as current /usr is reiserfs on LVM, and / is ext3 on > simple partition - ie, *not* the 'same filesystem’? Doesn’t matter. The type of file system is not visible to the copying program: to it, a file is a file is a file. Well, for present purposes anyway. I think you can interpret file-system as identical to partition here. > ...

Indeed. I hope you don’t have experience of cp failing to copy what it should. > Sorry for all the questions, I promise this will be the last one on this > subject... It’s how we learn, so don’t worry about it. :-) -- Regards Peter
