Description
R interface for the 'netstat' command line utility used to retrieve and parse commonly used network statistics, including available and in-use transmission control protocol (TCP) ports. Primers offering technical background information on the 'netstat' command line utility are available in the "Linux System Administrator's Manual" by Michael Kerrisk (2014) <https://man7.org/linux/man-pages/man8/netstat.8.html>, and on the Microsoft website (2017) <https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/netstat>.

Find a free TCP port using free_port()
free_port()
## [1] 14415
free_port()returns an available TCP port from Internet Assigned Numbers Authority (IANA) listed unassigned ports.free_port()will not return any TCP port currently in use - sofree_port()can safely be used to allocate a ports programmatically without collisions - great for automated testing or browser automation in general.
