traceroute:tldr:57604

The command "traceroute" is a network diagnostic tool that allows you to trace the route that packets take from your local machine to a destination host on a network. It helps identify the network nodes or routers that the packets pass through, and measures the time it takes for the packets to reach each node.

Here is a breakdown of the given command:

• "traceroute" is the command itself.
• "-q" specifies the number of probes (packets) to send per hop (network node). In this case, it uses a variable ${5} to indicate the number of probes.
• ${host} is also a variable that represents the destination host or IP address to which the traceroute is being performed.

So, the command is essentially running a traceroute with a variable number of probes ${5} to the specified host or IP address ${host}. The actual value of ${5} and ${host} will be provided when executing the command.
