The shell script automatically configures dual Nic binding

The shell script automatically configures dual-nic binding configuration dual-nic binding is one of the basic operations of O & M. The first configuration will be very rare, and the tenth configuration will be felt like a roll, 30th configuration can be done in two minutes, but there will be a feeling of vomiting blood during the 100th configuration. What should I do? Decisive lazy principle, script writing, automatic configuration.

It can be done in two minutes when you are the most skilled. Now it can be done in two seconds. This is the speed, and this is the efficiency.
