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

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

Challenge: When running commands or scripts, error messages (stderr) often appear mixed with normal output (stdout), making log analysis and debugging difficult.

The Solution: Redirect standard error to standard output using the `2>&1` shell construct.

your_command &> output.log

Why it works: The `&>` operator is a shorthand for `2>&1`, which redirects file descriptor 2 (stderr) to file descriptor 1 (stdout). This consolidates both standard output and standard error into a single file, simplifying log management.

Pro-Tip: You can also use `your_command > output.log 2>&1` to achieve the same result, explicitly redirecting stdout first and then stderr to stdout.
