% du -sh --max-depth=1 directoryname



Will give the total size, otherwise you'll list every file in the tree.

(Mac-related; act accordingly.)



One of the Mac's little features is Time Machine, their hourly incremental
backup program which, I understand, behaves like rsync, in that each time it
runs it only actually copies changed files and maintains only a tree of
links to the unchanged ones. I have a tree of approx 490GB that needs to be
shifted to another disk. When this tree is looked at via the UI it is shown
as 13TB big, thanks to all the links being expanded in the process.



I have tried cp -R to copy a single day's subtree and the result looked like
it was copying files not links. I get lost trying to sort out symbolic v
hard links and so on, hard though it may be to believe.



What syntax would allow me to just shift the whole tree onto another device
safely, please? And to determine the tree's actual (unexpanded) size?


% du -sh directoryname

This shows directory sizes (du stands for disk usage).
"man du" should tell you about more options.

You can save yourself some typing if you drop the --max-depth=1

Many thanks everybody - the great file transfer is underway with reassuring
'cp symlink:.... File exists' every now and then. The Mac cp -a-ing
through the tree to my little NAS-alike (NSA310) and trying to do anything
on it while this has been going on has been unbelievably slow: 20 second
waits to change tabs in a browser - like an old XP installation ( I know
because I have one and it's going to be Ubuntu-ed or Mint-ed tomorrow,
depending on which distro I have will still run on a 2005 Celeron...).

?Cheers and thanks again,
