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

Challenge: When running commands or scripts, standard output (stdout) and error messages (stderr) are often displayed separately, making it difficult to capture all relevant information in a single log file or pipe the combined output to another command.

The Solution: Redirect both standard output and standard error to a single stream using the `2>&1` 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. `2>&1` tells the shell to redirect file descriptor 2 to the same location as file descriptor 1. The `&>` syntax is a shorthand for this redirection.

Pro-Tip: For even more control, you can use `tee` to both display the output on the terminal and write it to a file simultaneously: `your_command 2>&1 | tee output.log`
