ip-rule:tldr:7bfe2
The command "sudo ip rule delete to ${192-168-178-2-32}" is attempting to delete an IP rule in a Linux system using the "ip" command with root privileges (sudo).
In this case, the rule being deleted is specified by the "to" parameter, which is set to "${192-168-178-2-32}".
However, it seems that there is an error in the IP address being used. The syntax "${192-168-178-2-32}" suggests that it is attempting to subtract 168, 178, 2, and 32 from 192, which is not a valid IP address format.
Normally, the "to" parameter should specify an IP address or a subnet to match against the destination IP address of packets. For example, "to 192.168.1.0/24" would match packets going to any IP address in the 192.168.1.0/24 subnet.
So, in summary, this command is intended to delete an IP rule based on the destination IP address, but the specified address seems to be incorrect.
