Mac安装sshpass

网上好多都失效了，2019-11-20以下方法亲测可行。

brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

安装成功后执行 sshpass出现以下效果，说明安装成功。

➜  ~ sshpass
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

   -P prompt     Which string should sshpass search for to 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

安装成功了，那就把密码记下来吧

vim ~/.bashrc

alias jump="sshpass -p '666' ssh host"

载入文件 source ~/.bashrc, 具体是哪个文件根据自身情况决定，我把.bashrc 加在了.zshrc里，所以我执行的是source ~/.zshrc。

接下来就是验证成果是时候了。
