Quick Tip

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

Challenge: When running commands that produce both standard output (stdout) and error messages (stderr), it can be cumbersome to track both. You might want to redirect them to a single file for easier analysis or to avoid interleaved output on your terminal.

The Solution: Use the `2>&1` redirection operator to merge stderr into stdout.

your_command &> output.log # or more explicitly: your_command > output.log 2>&1

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

Pro-Tip: For even cleaner redirection, you can use `&>` which is a shorthand for `>&` and achieves the same result of redirecting both stdout and stderr to the specified file.
