Create an SSH connection shortcut

The normal SSH connection command is: SSH uname@domain.com (or SSH domain.com-l uname)
In fact, you can configure a more concise method to create a shortcut for an SSH connection:
The creation method is simple. You only need to edit one file ~ /. Ssh/config (if the file does not exist, you can create it yourself)
Add the following content to the file:

Copy content to clipboard

Code:

Host test1
Hostname domain.com
User uname

Host Test2
Hostname 192.168.x.x
User ABC

...

You can write all the machines that you need to connect frequently.
After saving the file, you can use the shortcut to log on to ssh. The logon command is SSH test1 (or SSH Test2)
