    Understand how to Redirect stdin, stdout, and stderr in Bash

    bashBash

    Maybe you’ve seen something like 2>&1 at the end of a bash command before. What does that even mean? In this lesson, we’ll learn what stdin, stdout, and stderr are. From there, we’ll see that stdin, stdout, and stderr can be referenced by their file descriptors (0, 1, and 2) and are all just streams that can be directed however we want.
