Quick Tip

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

Challenge: When running commands or scripts, error messages (stderr) often get mixed with the standard output (stdout), making it difficult to parse logs or redirect output effectively.

The Solution: Redirecting stderr to stdout allows you to capture both streams of output in a single destination.

command > output.log 2>&1

Why it works: The `>` operator redirects stdout to `output.log`. The `2>&1` then redirects file descriptor 2 (stderr) to file descriptor 1 (which is currently pointing to `output.log`).

Pro-Tip: For more complex scenarios where you want to append to a log file instead of overwriting it, use `>>` for stdout: command >> output.log 2>&1
