mysql无密码本地备份/远程还原

Question

I am trying to backup local database and restore it on remote server without showing passwords

mysqldump -u local_user -pPWD my_db | mysql -u remote_user -pPWD -h IP -C T

, but first, I need to login and created a database to restore to on remote server:

mysql -u remote_user -pPWD -h IP -e "create database T;"

I've created extra.my.cnf on both, local server A and remote server B.

-rw-r--r-- 1 root root   37 Aug 14 11:35 extra.my.cnf  <----- A
-rw-r--r-- 1 root root 75 Aug 14 18:49 extra.my.cnf    <----- B

Content of the remote extra.my.cnf (on B):

# cat extra.my.cnf
[client]
user=remote_user
password="PWD"

[mysqldump]
user=remote_user
password="PWD"

Using --defaults-extra-file does not work.

mysql --defaults-extra-file=/path/to/extra.my.cnf -h IP

Could not open required defaults file: /path/to/extra.my.cnf
Fatal error in defaults handling. Program aborted

What am I missing???
