1：sshpass下載與安裝
yum安裝：
yum install sshpass
若yum安裝不上，則用下面方法
https://sourceforge.net/projects/sshpass/files/
or
https://pan.baidu.com/s/1pLNxeLd
or
wget http://sourceforge.net/projects/sshpass/files/latest/download -O sshpass.tar.gz
2：下載后，解壓，安裝
tar -zxvf sshpass-1.06.tar.gz
cd sshpass-1.06
./configure
make
make install
3：使用命令
sshpass -p 123456 scp /home/file.txt root@10.0.0.37:/home/copy
后面這個是 “Are you sure you want to continue connecting (yes/no)”使得這個自動接受，若不加，則成功不了
4：腳本
#!/bin/bash
password=123456
user=root
ip=10.0.0.37
file=/home/file.txt
sshpass -p $password scp file $user@$ip:/home/copy/
