What is an IT operations engineer?

1, Linux basic commands and scripts: shell is the basic requirement, and perl or python is best understood. If you don't know the script, how can you make repetitive work simple?

2. System monitoring command: The purpose is to obtain the current running status of the system and know how to analyze and troubleshoot. The system is tuned and understands the principle, and knows why the parameters should be adjusted to a certain value.

3. Network monitoring command: The reason is the same as the second point, but the focus is on the network. You also need to know the principle and tuning. If you don't know much, you can't copy previous experience.
