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

Challenge: When running commands or scripts, you often get output mixed between standard output (stdout) and standard error (stderr). This can make it difficult to read logs or redirect output effectively.

The Solution: Redirect stderr to stdout using the `2>&1` construct.

your_command &> output.log # or more explicitly your_command > output.log 2>&1

Why it works: `2>` redirects file descriptor 2 (stderr) to the file specified, and `&1` tells it to redirect to file descriptor 1 (stdout). By placing `2>&1` after the stdout redirection (`> output.log`), you ensure both streams are captured in the same file.

Pro-Tip: The `&>` shorthand is a convenient way to redirect both stdout and stderr to a file, equivalent to `> file 2>&1`.
