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

Challenge: When running commands or scripts, you often get both standard output (stdout) and standard error (stderr) messages. If you’re trying to redirect output to a file or pipe it to another command, these interleaved messages can make analysis difficult or lead to unexpected results.

The Solution: Redirect stderr to stdout using the `2>&1` construct.

your_command_here &> output.log # OR your_command_here > output.log 2>&1

Why it works: File descriptor 1 (stdout) and file descriptor 2 (stderr) represent the two primary output streams. By redirecting file descriptor 2 to file descriptor 1 (`2>&1`), all error messages are appended to the standard output stream, allowing you to capture both in a single destination.

Pro-Tip: Use `&>` as a shorthand for `> … 2>&1` when redirecting both streams to the same file.
