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’s often difficult to manage or analyze them separately. This can make log inspection tedious and error-prone.

The Solution: Redirect both standard error (stderr) and standard output (stdout) to a single destination using the `2>&1` redirection operator.

your_command &> output_and_error.log # Or, more explicitly: your_command > output.log 2>&1

Why it works: The `>` redirects stdout (file descriptor 1) to a file. The `2>&1` then redirects stderr (file descriptor 2) to wherever stdout is currently being directed (in this case, the same log file). The `&>` is a shorthand for this common operation.

Pro-Tip: Use `| tee output.log 2>&1` to see the output on your terminal *and* save it to a file simultaneously.
