The command "ping" is used to check the connectivity between two devices over a network using Internet Control Message Protocol (ICMP) echo requests and replies.
The specific command "ping -i ${seconds} ${host}" allows you to customize the interval between ICMP echo requests being sent to a specific destination host.
-
The "-i" flag is used to set the interval between each echo request to the specified value in seconds. ${seconds} denotes the value you want to set as the interval.
-
${host} represents the target host or IP address that you want to ping. It can be a domain name (e.g., google.com) or an IP address (e.g., 192.168.1.1).
By executing this command, your system will send ICMP echo requests to the specified host at the specified interval, and you will receive ICMP echo replies from the host if it is reachable. The command will continue running until you manually stop it by pressing Ctrl + C.
