关于b脚本的问题

我使用的是 Ubuntu 16.04。我编写了一个基本的 bash 文件，可以自动将我登录到 SSH 服务器。如果 SSH 无法连接到服务器，是否有办法添加一条消息，提示“连接失败”？可能是命令if？我已将文件放在GitHub。

添加脚本

#!/bin/sh
#I wrote this little bash script for people.
#It's just for people that don't know how to make an auto login script for SSH.
clear
echo "Welcome, $USER !"
echo "Connecting to SSH server..."
sshpass -p "passwordhere" ssh -o StrictHostKeyChecking=no user@host

而sshpass -p "passwordhere" ssh -o StrictHostKeyChecking=no user@host不是

if $(sshpass -p "passwordhere" ssh -o StrictHostKeyChecking=no user@host); then echo "Success!"; else echo "Bother.  Didn't work."; fi
