用expect实现自动输入SSH的SCP信息，且不需要另外的文件

#!/bin/sh



if [ $# != 2 ] ; then  
echo "USAGE: $0 remote_ip serverXXXXX"  
echo " e.g.: $0 1.2.3.4 serverxxxx"  
exit 1;  
fi  

host_ip=$1
server_port=$2
user_name="user_name"
password="password"
server_path="/xx/xxx"
src_path="${server_path}/${server_port}"

###fork expect send password and exec scp command

expect << EOF
set timeout 30
spawn scp -r $src_path $user_name@$host_ip:$server_path
expect "password:"
send "${password}\r"
expect eof 
EOF
