Hi.

LOCAL "btrfs send/receive"

btrfs send -p /tmp/tmp.hkAa8XaliZ/btrfssnapshot/root/root-2016-12-18_15:10:01.40 /tmp/tmp.hkAa8XaliZ/btrfssnapshot/root/root-2016-12-19_19:44:00.41 | btrfs receive /tmp/tmp.NRYgYVC3p6/btrfsreceive/root/.part/


REMOTE "btrfs send/receive"

btrfs send -p /tmp/tmp.BTACBk7xuK/btrfssnapshot/root/root-2016-12-18_15:10:01.40 /tmp/tmp.BTACBk7xuK/btrfssnapshot/root/root-2016-12-19_19:44:00.41 | ssh root@exnetold.gdb.it btrfsManage REMOTE_RECEIVE /dev/sda3 root root-2016-12-19_19:44:00.41

Remote btrfsManage script (btrfsManage REMOTE_RECEIVE /dev/sda3 root root-2016-12-19_19:44:00.41) executes 

cat - | btrfs receive /tmp/tmp.Wd5togIiaL/btrfsreceive/root/.part/


The waiting for the end of a command, in shell script, is implicit/automatic.


Regards.
