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

Challenge: When running commands in Linux, you often see error messages (stderr) and normal output (stdout) appearing separately in your terminal. This can make it difficult to capture all relevant information, especially when redirecting output to a file or piping it to another command.

The Solution: Use the `2>&1` redirection trick to merge standard error (file descriptor 2) with standard output (file descriptor 1).

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

Why it works: `2>&1` tells the shell to redirect file descriptor 2 (stderr) to the same destination as file descriptor 1 (stdout). The `&>` shorthand achieves the same result in a more concise way.

Pro-Tip: Use `tee` in conjunction with this to see the output on your screen *and* save it to a file simultaneously: your_command &> output.log | tee output.log
