ssh: Agent forwarding: Forward the authentication information to the remote machine (see `man ssh_config` for available options).

$ ssh -A ${username}@${remote_host}

try on your machine

This command is used to establish an SSH (Secure Shell) connection to a remote host. Let's break down the components of this command:

ssh: It is the command used to initiate an SSH connection.
-A: This option enables SSH agent forwarding. It enables the user to use their local SSH keys on the remote host. This is useful when logging into a remote server and then needing to SSH from there to another server, without having to manually copy the private key file to the intermediate server.
${username}: This is a placeholder variable that should be replaced with the actual username you want to use to connect to the remote host. For example, if the username is "john", you would replace ${username} with john.
@: It is the separator used to specify the username and the remote host.
${remote_host}: This is another placeholder variable that should be replaced with the actual hostname or IP address of the remote host you want to connect to. For example, if the remote host is "example.com", you would replace ${remote_host} with example.com.

Putting it all together, this command will use SSH agent forwarding to establish an SSH connection to the remote host specified by ${remote_host}, using the username specified by ${username}.
