Quick Tip

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

Challenge: When running commands or scripts, error messages (stderr) and normal output (stdout) are often displayed separately. This can make it difficult to capture and analyze all output consistently, especially when redirecting to files or piping to other commands.

The Solution: Redirect both standard error (stderr) and standard output (stdout) to a single destination using the `2>&1` construct.

your_command_here &> output.log

Why it works: The `&>` is a shorthand for `> file 2>&1`. It redirects file descriptor 1 (stdout) to `output.log`, and then redirects file descriptor 2 (stderr) to the same location as file descriptor 1 (which is now `output.log`).

Pro-Tip: For more granular control, you can redirect only stderr to stdout (e.g., `your_command_here 2>&1 | some_other_command`) or send both to different files (e.g., `your_command_here > stdout.log 2> stderr.log`).
