Answer 1

To invoke program a and use its output as the input for program b, you can use the pipe operator (|) in the command line.

Step-by-step explanation:

To invoke program a and use its output as the input for program b, you can use the pipe operator (|) in the command line. Here's the command you would type: a | b

This will send the output of program A as the input to program b, allowing them to work together.

The command line is a text interface for your computer. It's a program that takes in commands, which it passes on to the computer's operating system to run. From the command line, you can navigate through files and folders on your computer, just as you would with Windows Explorer on Windows or Finder on Mac OS.

CMD is an abbreviation of the word “command” and is used when referencing Windows command processor, aka Command Prompt. CMD is a powerful tool for Windows operating systems that allows users to interact with the computer using text-based CMD commands through the command line interface.
