I have a tar.gz file that has multiple dirs and files inside. I need to copy and extract a specific dir from it to a remote host.

I know how to do it with a single file, but have trouble with multiple files in a single command:

    tar zxOf /mnt/debug.tar.gz libr.so | ssh $MY_IP 'cat > /local/libr.so'

I currently workaround by extracting the whole dir locally, then use scp to copy:

tar -zxf /mnt/debug.tar.gz -C utils/foo --strip-components=1 tools/

Thanks!

    If you don't mind the network overhead, you can do stuff like cat debug.tar.gz | ssh remotehost tar xfz - -C /local foo bar baz - ie stream the tar file to the remote host and do the tar extraction there. It doesn't use disk space, but it does use network bandwidth. Aug 22, 2016 at 12:44

How about a simple shell loop:

files="first second third"
for f in files; do
  tar xf thearchive.tar $f | ssh otherhost "cat > $f"
done
