When we use ssh public key authentication, we usually add relevant settings in ~/.ssh/config.
If some are used by the company or at home, can multiple configs be used?
In fact, it is possible. We can use git to load the company-shared, version-controlled config through Include.

The following is a schematic setting of ~/.ssh/config.

Include ~/.ssh/keys/office_config

WebShell Function Introduction and Precautions

I suddenly wanted to introduce what is WebShell, so I found one on the Internet. Its functions are quite good. But I still wanted some features, so I spent three nights making some small optimizations for him. If you haven't heard of WebShell yet, take a look at this video. If you like my optimized version, please give me a like, thank you.
