What others think

I like this use of tar and use it a lot on local machines to copy entire directory trees to some other place...

e.g.: tar cpf - . | (cd /somewhere/else; tar xvf -)

I suppose this can work the other way with:

tar cpf - . | ssh somehost 'cd /some/directory && tar xvpf -'

perhaps use tar xvBf - to ensure a good copy. B performs re-blocking.

Its worth mentioning that if you have links in the directory tree you are copying then check them after the copy. Soft links may break if pointing outside the directory tree being copied. Hard links will copy the 'pointed at' files... good, but bad if huge.

great command...

Nice. However in most cases scp -r should do the same and is a bit easier to type.

ha.... true scp -r will work too :)

Comment by finkployd 223 weeks and 5 days ago

For cases where scp -r doesn't work properly, there's rsync, as in:

rsync -av user@somemachine:somedir .

Of course, rsync tries to use 'rsh' by default. To get it to use ssh, use either

RSYNC_RSH=`which ssh` rsync -av user@somemachine:somedir .

or

rsync --rsh=`which ssh` -av user@somemachine:somedir .
