What programming language has the capability to automatically execute terminal commands?

Say I want to scan a Wifi network for IP addresses using arp -a and print those IP addresses to the screen?

What programming language is best equipped to do this? Python? Ruby?

Answer 1

Almost all modern programming languages has the capability to execute terminal commands (in python you can use the os or subprocess modules).
