循环完成后终端脚本不会中断

Question

我正在尝试编写一个终端脚本；成功后我想触发一个功能，当它失败时我想发送警报。该脚本可以正常工作，除非成功后它会继续运行 'done; 之后的命令；线。不确定正确的语法或正确的写法。

我只希望完成后的命令在失败时处理，而不是在成功时处理。

check_connection_wireguard(){
n=0
until [ "$n" -ge 1 ]
do
   ping -c 1 $remoteIdrac &> /dev/null && echo 'Success' && break
   n=$((n+1))
   echo "Connection Failed Attempt" $n
   sleep 15
done

   ssh $localIp wg-quick down $wireguardInterface
   ssh $localIp /usr/local/emhttp/webGui/scripts/notify -i alert -s \"Backup Remote Connection\" -d \"Backup Operation failed to connect\"
}

所以我用下面的代码解决了，只是添加了一个 if 语句，但想知道是否有比下面更优雅的解决方案。

check_connection_wireguard(){
n=0
until [ "$n" -ge 1 ]
do
  ping -c 1 10.10.20.100 &> /dev/null && echo 'Success' && break
  n=$((n+1))
  echo "Connection Failed Attempt" $n
  sleep 15

    if [[ $n > 1 ]]; then
    ssh $localIp wg-quick down $wireguardInterface
    ssh $localIp /usr/local/emhttp/webGui/scripts/notify -i alert -s \"Backup Remote Connection\" -d \"Backup Operation failed to connect\"
    fi
done


}

break 只是跳出循环。您希望 return 在成功时跳出函数：

check_connection_wireguard(){
n=0
until [ "$n" -ge 1 ]
do
   ping -c 1 $remoteIdrac &> /dev/null && echo 'Success' && return
   n=$((n+1))
   echo "Connection Failed Attempt" $n
   sleep 15
done

   ssh $localIp wg-quick down $wireguardInterface
   ssh $localIp /usr/local/emhttp/webGui/scripts/notify -i alert -s \"Backup Remote Connection\" -d \"Backup Operation failed to connect\"
}
