FAQs on the exercise stdin, stdout, and stderr

The introduction to standard input (stdin), standard output (stdout), and standard error (stderr) in this lesson seem to be the same thing as the usual input, output, and error. Why the distinction of standard ?

Hello! Could someone explain me below? I didn’t understand one moment. Here

sort deserts.txt | uniq > **uniq-deserts.txt**

the file uniq-deserts.txt is created during the command execution or this file was created before and command just re-writes it’s content with the sorted deserts?
thank you!

I guess shell prompt is nothing but $ sign here so everything we write in CLI is only after shell prompt. When shell prompt is visible then it means it is ready to accept the lines of codes for execution.
