    This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

我从未尝试过在bash中使用“ getopts”，我第一次尝试您可以在上方看到它，但实际上是失败的。

任何帮助将不胜感激，

谢谢

1 个答案:

答案 0 :(得分：1)

您可以避免将getopts放在一起，而只需使用正则表达式即可。

myvar=$(echo "$@" | sed 's/.*-ip\s\+\([0-9a-zA-Z\.]\+\)\s*.*/\1/g')

将-ip之后的内容加载到myvar中。如果只需要与IP匹配的内容，则相应地调整正则表达式。
