ping:tldr:71c78
The command "ping -a ${host}" is used to check the network connectivity between your computer and a specified "host" (typically a website or IP address). Here is a breakdown of the command:
-
"ping": This is the command used to send a network request, called an Internet Control Message Protocol (ICMP) echo request, to the specified host.
-
"-a": This option is used to resolve IP addresses to their corresponding hostnames. It attempts to retrieve the hostname associated with the IP address of the host being pinged.
-
"${host}": This is a placeholder for the actual hostname or IP address of the host you want to ping. You should replace "${host}" with the desired hostname or IP address when executing the command.
In summary, this command allows you to ping a host and also obtain its hostname if it is available.
