Quick Tip

Taming Terminal Noise: Unified Logging with `2>&1`

Challenge: When running commands or scripts that produce both standard output (stdout) and standard error (stderr), it can be difficult to capture and analyze both streams effectively, especially when redirecting output to a file.

The Solution: Redirect both stdout and stderr to a single file using the `2>&1` redirection operator.

your_command > output.log 2>&1

Why it works: The `>` redirects stdout (file descriptor 1) to output.log. The `2>&1` then redirects stderr (file descriptor 2) to wherever stdout is currently being redirected (in this case, output.log).

Pro-Tip: You can also use `&>` as a shorthand for `> … 2>&1` in Bash and Zsh: your_command &> output.log
