Ssh-copy-id to set different port methods

Ssh-copy-id is a handy tool for setting up Peer-to-peer logins between machines (without having to enter a password every time), Ssh-copy-id's default port is 22 and ssh, but sometimes we change SSH ports to other ports to consider security issues. Ssh-copy-id does not provide parameters for setting ports, looks at the Ssh-copy-id code (a shell program), and finds that the port can be set using the following methods:

The code is as follows	Copy Code
Ssh-copy-id "-P port User@host"

This allows the Ssh-copy-id to use a different port.
