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

Challenge: When running commands or scripts that produce both standard output (stdout) and error messages (stderr), it can be messy to have them interleaved or mixed, making log analysis difficult.

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

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

Why it works: File descriptor 1 represents stdout, and file descriptor 2 represents stderr. By redirecting stderr (2) to wherever stdout (1) is currently directed, both streams are consolidated.

Pro-Tip: Use `&>` as a shorthand for `&1` to redirect both stdout and stderr to a file.
