sshpass: 用于非交互的ssh 密码验证

ssh登陆不能在命令行中指定密码,也不能以shell中随处可见的,sshpass 的出现,解决了这一问题。它允许你用 -p 参数指定明文密码,然后直接登录远程服务器。 它支持密码从命令行,文件,环境变量中读取
$> sshpass -h
Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
   -f filename Take password to use from file
   -d number Use number as file descriptor for getting password
   -p password Provide password as argument (security unwise)
   -e Password is passed as env-var “SSHPASS”
   With no parameters – password will be taken from stdin
   -h Show help (this screen)
   -V Print version information
At most one of -f, -d, -p or -e should be used
sshpass [-f|-d|-p|-e] [-hV] command parameters 中的 command parameters 和使用交互式密码验证的使用方法相同
#从命令行方式传递密码
    $> sshpass -p user_password ssh user_name@192.168..1.2
    $> sshpass -p user_password scp -P22 192.168.1.2:/home/test/t .
#从文件读取密码
    $> echo “user_password” > user.passwd
    $> sshpass -f user.passwd ssh user_name@192.168..1.2
#从环境变量获取密码
    $> export SSHPASS=”user_password”
    $> sshpass -e ssh user_name@192.168..1.2
