Stdout, Stdin, and Stderr
Last updated
What is Stdout, Stdin, and Stderr?
Linux processes use three standard data streams: STDIN (input), STDOUT (output), and STDERR (error messages). STDOUT handles normal command output while STDERR specifically handles error messages. You can redirect these streams using operators like > for stdout and 2> for stderr, allowing separate handling of normal output and errors for better scripting and debugging.
