Command to create a key and immediately upload it to the server?

Question

linux

Good day! One person showed me the command to create a key. In order not to enter the password constantly. But he did it somehow cunningly with one command. I remember only ssh: -[some parameter] 192.168.1.1 [something further].
And all I could enter without a password, it did not generate anything.

Apparently the key has already been created. It doesn't take much to do what you've described.
First, generate a key with the ssh-keygen command . This must be done once if such a key has not yet been made. If it is, then you don't need to do it.
Next , ssh-copy-id [email protected] will transfer your key to the server. After that, you can connect without a password with the command ssh [email protected]
