Usage="this tool is a simple wrapper to scp to copy local folder of metad to another (remote)place \n \
    it afford 4 options:    \n \
        1. -f (from) local metad dir \n \
        2. -t (to) remote destination \n \
        3. -u (update) any configs need to be changed \n \
            different configs should be separated by ':' \n \
            each config has to be the form of "local_ip=172.0.0.1" \n \
        \n \
    for example \n \
        ./meta-transfer-tools.sh -f /path-to-src/metad1 -t bob@172.0.0.1:/path-to-dst -u local_ip=172.0.0.1:port=10086 \n \
