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

Challenge: When running commands in the Linux terminal, especially in scripts, you often encounter both standard output (stdout) and standard error (stderr) messages. These can get interleaved, making it difficult to read, redirect, or log them effectively.

The Solution: Use the `2>&1` redirection operator to merge standard error into standard output.

your_command &> output.log

Why it works: The `&>` is a shorthand for `> 2>&1`. It redirects both standard output (file descriptor 1) and standard error (file descriptor 2) to the specified file, `output.log`. This ensures all messages from your command are captured in a single, organized log file.

Pro-Tip: For more granular control, you can use `your_command > output.txt 2> error.txt` to send stdout and stderr to separate files.
