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

Challenge: When running commands or scripts, both standard output (stdout) and standard error (stderr) messages can appear interleaved, making it difficult to read or capture them separately for analysis.

The Solution: Redirect both standard output and standard error to a single file or stream using the `2>&1` construct.

your_command ... > output.log 2>&1

Why it works: `>` redirects stdout (file descriptor 1) to `output.log`. `2>&1` then redirects stderr (file descriptor 2) to the same location as stdout (file descriptor 1), ensuring all output goes to `output.log`.

Pro-Tip: You can also use `&>` as a shorthand for `&> output.log` in Bash to achieve the same result.
