Tame Terminal Noise: Redirect `stderr` with `2>&1` for Unified Logging

Challenge: When running commands or scripts, error messages (from `stderr`) often get mixed with standard output (`stdout`), making log analysis and debugging difficult.

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

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

Why it works: In shell redirection, file descriptor 1 (`stdout`) and file descriptor 2 (`stderr`) are standard. The `&>` operator is a shorthand for redirecting both `stdout` and `stderr` to the specified file. The `> output.log 2>&1` explicitly redirects `stdout` (1) to `output.log` and then redirects `stderr` (2) to the same location as `stdout` (1).

Pro-Tip: Use `| tee output.log` instead of `&> output.log` if you want to see the output on your terminal *and* save it to a file simultaneously.
