Couple of cool remote ssh commands for your UNIX arsenal

CLI, Reference, Shell Script, Unix
Here is a easy way to copy an entire directory tree from one Unix machine to another, while retaining the permisssions and ownership, using ssh as the middle man. Assuming that you want to copy everything under source_directory to destination_directory on another machine here is the command you would issue on the source machine (first cd to the directory containing source_directory): tar -cf - source_directory/ | ssh userid@your.destination.machine.com "cd /somedir/destination_directory ; tar -xvlpf -" or if you want to copy everything from the remote server's source directory to the local machine's destination directory: ssh userid@your.source.machine.com "(cd /somedir/source_directory ; tar -cf - .)" |(cd /somedir/destination_directory ; tar -xvlf -) Here is another similar command that allows you to backup a HD partition to another host via ssh: dd bs=1M if=/dev/sdb |…

So I like to turn Spotlight off ASAP. Here is how:Edit /etc/hostconfig (don't forget to sudo) and change…
