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

Challenge: When running commands that produce both standard output (stdout) and standard error (stderr), it can be difficult to manage and analyze them, especially when redirecting output to a file. You might want to capture both in a single log file for easier troubleshooting.

The Solution: Redirect both stdout and stderr to a single destination using the `2>&1` syntax.

your_command_here 2>&1 | tee output.log

Why it works: The `2>&1` part redirects file descriptor 2 (stderr) to file descriptor 1 (stdout). Then, the pipe `|` sends this combined stream to `tee`, which both displays it on the terminal and writes it to the specified file (`output.log`).

Pro-Tip: For truly silent operation where you don’t want anything shown on the terminal, simply use `your_command_here 2>&1 > output.log`.
