The command "ping -O ${host}" is used to send an ICMP echo request to a host or IP address, notifying the user when the host becomes reachable. Here's a breakdown of the components:
- "ping" is a command used to send an ICMP echo request to a specific host or IP address and receive responses.
- "-O" is an option or flag that instructs the ping command to wait for a reply after sending each packet and display the result.
- "${host}" is a placeholder that represents the host or IP address you would specify when executing the command. You need to replace ${host} with the actual host or IP address you want to ping.
Overall, this command allows you to continuously monitor the reachability of the specified host by repeatedly sending echo requests and displaying the response.
