Quick Tip

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

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

The Solution: Redirect both stdout and stderr to a single location using the `2>&1` syntax.

your_command > output.log 2>&1

Why it works: The `>` operator redirects stdout (file descriptor 1). The `2>&1` then redirects stderr (file descriptor 2) to the same place as stdout (file descriptor 1). This consolidates all output into one log file.

Pro-Tip: For commands that might produce a lot of output, you can pipe this unified stream to `tee` to view it on the screen while also saving it to a file: `your_command &> >(tee unified_output.log)`
