$ unshare --net ${command} ${command_arguments}

try on your machine

The unshare --net command is used to run a given command (${command}) with its arguments (${command_arguments}) in a new network namespace.

A network namespace is a feature of the Linux kernel that allows processes to have their own separate network stack. This means that processes running in different network namespaces can have their own network interfaces, IP addresses, routing tables, firewall rules, and more.

By using unshare --net, we create a new network namespace and run a specific command within it. The ${command} represents the command that will be executed, while ${command_arguments} represents any additional arguments that may be passed to the command.

Running a command with unshare --net is useful for isolating network-related activities of a process. It is commonly used in scenarios such as testing network configurations, containerization, or running network services in a restricted environment.
