Analysis of information sources in references of the Wikipedia article "Shell (computing)" in English language version.
Mr Pouzin created a program called RUNCOM that helped users automate tedious and repetitive commands. That program, which he described as a "shell" around the computer's whirring innards, gave inspiration—and a name—to an entire class of software tools, called command-line shells, that still lurk below the surface of modern operating systems.
You can run commands on one or hundreds of computers with a single PowerShell command. Windows PowerShell supports remote computing by using various technologies, including WMI, RPC, and WS-Management.
