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

Challenge: When running commands or scripts that produce both standard output (stdout) and error output (stderr), it can be cumbersome to manage and analyze these separate streams, especially when redirecting output to a file.

The Solution: Redirecting both stdout and stderr to the same destination using `2>&1`.

your_command_here > output.log 2>&1

Why it works: File descriptor `1` is stdout, and `2` is stderr. `2>&1` tells the shell to redirect file descriptor `2` (stderr) to wherever file descriptor `1` (stdout) is currently pointing. In this case, stdout is already redirected to `output.log`, so stderr follows suit.

Pro-Tip: To append both stdout and stderr to a file, use your_command_here >> output.log 2>&1.
