Silence the Noise: Unified `stderr` and `stdout` Logging

Challenge: When running complex commands or scripts, you often get output mixed between standard output (stdout) and standard error (stderr). This can make it difficult to analyze logs or capture all relevant information in a single file.

The Solution: Redirect both stderr and stdout to a single destination using the `2>&1` redirection.

your_command_here 2>&1 | tee logfile.txt

Why it works: File descriptor `2` represents stderr, and `&1` means “the same place as file descriptor 1” (which is stdout). By redirecting stderr to stdout ( `2>&1` ), and then piping that combined stream to `tee`, you capture all output, both successful and error messages, into `logfile.txt` while also displaying it on your terminal.

Pro-Tip: Use `your_command_here &> logfile.txt` as a shorthand for `your_command_here > logfile.txt 2>&1` when you want to redirect both to the same file without piping.
