源端为阿里云数据库时报错，未知的 ARS 命令

[qD6HrDvBtUuE9nH]

redis-shake3.18 同步 Redis 数据时提示未找到命令，影响控制台的观察，有没有方案解决这类报错告警信息，源和目标端都是redis5.0 社区版本.
报错提示：

你这是在尝试从阿里云 Redis 迁出数据对吧，目前还不支持呢。阿里云会在所有命令前面添加 ars 字段，需要去除。

[suxb201]

已经原生支持去除。

[lazy666666]

请问怎么使用去除ARS呢？

[suxb201]

@lazy666666 现在代码默认去除

我测试了最新版4.0.5版本的redis-shake，发现增量复制的时候，还是报错

@lazy666666 确实忘记处理了，ARS 命令结构是 arg xxxx 真正命令，比如 set k v 会被包成 ars xxx set k v
所以你可以在这里改一下，如果是 arg 命令的话，去掉前两个元素，也欢迎交个 PR：

好嘞，感谢
