The command "echo" is used to display or print text on the command line interface or terminal. In this specific command, the text to be printed is enclosed within double quotes and stored in the variable "${declined_login_message}".
The ">" symbol is a redirect operator used to redirect the output of a command to a file. In this case, the output of the "echo" command will be redirected to the file named "/etc/nologin.txt".
So, the command essentially echoes the contents of the "declined_login_message" variable and saves it in the "/etc/nologin.txt" file.
