Quick Tip

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

Challenge: When running commands or scripts, error messages (stderr) often appear interleaved with normal output (stdout), making it difficult to read and analyze logs.

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

your_command &> combined_output.log

Why it works: The `&>` redirection operator is a shortcut for `2>&1`, meaning it redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout). This consolidates all output, both standard and error, into a single stream or file.

Pro-Tip: You can also use `your_command > output.log 2>&1` for a more explicit redirection, which is particularly useful when piping output.
