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

Challenge: When running commands or scripts that produce both standard output (stdout) and standard error (stderr), it can be difficult to track and analyze the information if it’s scattered across different output streams. This is especially true when redirecting output to a file for later review.

The Solution: Utilize the shell’s redirection capabilities to combine stderr with stdout.

your_command > output.log 2>&1

Why it works: The `2>&1` part of the command tells the shell to redirect file descriptor 2 (stderr) to the same location as file descriptor 1 (stdout). By redirecting stdout to `output.log` first, then redirecting stderr to where stdout is going, all output ends up in the single log file.

Pro-Tip: For even more granular control, you can redirect stderr to a separate file using `your_command > stdout.log 2> stderr.log`.
