**What does the command** `echo "Welcome to in28minutes $(hostname)" > /var/www/html/index.html` **do?** The command writes a message to the file `/var/www/html/index.html`. It includes the text `"Welcome to in28minutes"` followed by the machine's hostname. The `$(hostname)` part dynamically inserts the current hostname of the machine. Any existing content in the file will be replaced with this new message.
