The "finger" command is used to retrieve information about a user on a remote system. The "@" character is used to specify that the command should be executed on a remote host. In this particular command, the variable "${host}" is used to define the remote host's address.
So, if the value of "${host}" is "example.com", the command "finger @example.com" would be executed to retrieve information about a user on the remote host "example.com".
