sshpass 实现的SSH免交互密码登录和ARM移植
sshpass在ubuntu上的测试
安装：
sudo apt-get install sshpass
实例：
sshpass -p 'yourpassword' ssh root@192.168.5.103
这可以避免一次交互，
sshpass -p "root" ssh root@192.168.5.103
脚本的写法：
#!/bin/bash export SSHPASS='root' msg=$(sshpass -e ssh root@192.168.5.103 ls /home/root/) echo $msg
源码下载
网址：Non-interactive ssh password auth - Browse /sshpass at SourceForge.net
目前的最新版本是1.10，下载后解压
tar zxvf sshpass-1.10.tar.gz
交叉编译脚本：
文件命名为build.sh
#!/bin/bash
set -e# 配置交叉编译环境变量

命令行测试：
sshpass -p "password" ssh username@192.168.5.5
脚本测试：
#!/bin/sh
export SSHPASS='root'
msg=$(sshpass -e ssh root@192.168.5.103 ls /home/root/)
echo $msg文件发送测试
sshpass -p "lkmao" scp sshpass_test.sh lkmao@192.168.5.111:/home/lkmao/
