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
安装sshpass
curl -O -L http://downloads.sourceforge.net/project/sshpass/sshpass/1.06/sshpass-1.06.tar.gz && tar xvzf sshpass-1.06.tar.gz && cd sshpass-1.06 && ./configure && make && sudo make install
安装后执行sshpass -V查看版本
sshpass -V

Using"assword" as the default password prompt indicator.
sshpass -h查看帮助
Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters-f filename Take password to use from file
-d number Use number as file descriptor forgetting 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-P prompt Which string should sshpass search forto detect a password prompt-v Be verbose about what you're doing
-h Show help (this screen)-V Print version information
At most one of-f, -d, -p or -e should be used
sshpass 参数 SSH命令(ssh,sftp,scp等)。
参数:
-p password //将参数password作为密码。
-f passwordfile //提取文件passwordfile的第一行作为密码。
-d 使用数字作为文件描述符来获取密码
-e //将环境变量SSHPASS作为密码。
另外,对于ssh的第一次登陆,会提示:“Are you sure you want to continue connecting (yes/no)”,这时用sshpass会不好使,可以在ssh命令后面加上 -o StrictHostKeyChecking=no来解决。比如说上面的命令,就可以写作ssh -p efghi scp abc@192.168.0.5:/home/xxx/test /root -o StrictHostKeyChecking=no。
